Hillary Clinton on Friday defended her 2016 campaign strategy after 2020 Democratic presidential contender Pete Buttigieg criticized his party's previous nominee for being too hopeful and not understanding the struggles of everyday Americans.

"I really do believe that we always have to appeal to our better selves because the wolf is at the door, my friends," Clinton said during an appearance at the 10th Annual Women in the World New York Summit. "Negativity, despair, anxiety, resentment, anger, prejudice, that's part of human nature and the job of the leader is to appeal to us to be more than we can be on our own, to join hands in common effort."

"I was well aware that we had problems that we had to solve, but it's been my experience that anger, resent, prejudice are not strategies," the former first lady, secretary of state and senator from New York added. "They stop people from thinking. They don't enlist people in the common effort to try to find solutions."

Buttigieg, the mayor of South Bend, Ind., told the Washington Post in a profile published January that President Trump connected with the concerns of ordinary Americans in a way Clinton did not.

“Donald Trump got elected because, in his twisted way, he pointed out the huge troubles in our economy and our democracy,” he said. “At least he didn’t go around saying that America was already great, like Hillary did.”

A senior Clinton adviser blasted Buttigieg's comments last month via Twitter as "indefensible."

"[Hillary Clinton] ran on a belief in this country & the most progressive platform in modern political history. Trump ran on pessimism, racism, false promises, & vitriol. Interpret that how you want, but there are 66,000,000 people who disagree. Good luck," Nick Merrill tweeted.

"It's pretty simple. Slam HRC...lose my vote," and another who chimed in: "It is unfortunate when people as smart as @PeteButtigieg engage in this fantasy fiction about 2016. And as a gay American it is disappointing because @HillaryClinton ran a campaign which amongst its many values championed our community," Merrill also wrote.

Chevron agreed to pay $33 billion for Anadarko Petroleum on Friday, broadening its access to the largest oil region in the continental U.S. as President Trump pushes the country to produce enough fuel to meet its own energy needs.

The deal, which offers Anadarko investors $65 a share in cash and stock, expands Chevron's oil production in the Permian Basin, the oil-rich swath of land in western Texas and southeastern New Mexico that's 250 miles wide and about 300 miles long, as well as deepwater drilling in the Gulf of Mexico.

"We intend to accelerate activity in Anadarko's Permian acreage," Chevron CEO Michael Wirth, who hopes to complete the deal by the end of this year, told investors on Friday. "Getting more out of the Permian sooner is an important value driver."

For the San Ramon, Calif.-based company, which already controlled 2.2 million acres in the region and is adding 589,000 with the transaction, the driver isn't "getting bigger in the Permian, it's about getting better," Wirth said. That includes the the area's Delaware Basin, where Anadarko has operations.

Late last year, the U.S. Geological Survey identified an estimated 46 billion barrels of oil in two formations in the Delaware Basin, a development that left then-Interior Secretary Ryan Zinke confident "that American energy dominance is within our grasp."

The U.S. is the world's largest oil producer, outpacing both Russia and Saudi Arabia, thanks largely to technological advances that let producers extract oil from shale formations.

Achieving energy independence was one of Trump's signature campaign promises in 2016, a commitment based on concern that U.S. reliance on oil imports left the country more vulnerable and cost American jobs.

"We're ending the theft of American prosperity and rebuilding our beloved country," Trump said when he signed an executive order prompting energy independence just two months after taking office. "We will unlock job-producing natural gas, oil and shale energy."

Anadarko climbed 33 percent to $62.20 after the sale was announced Friday. Chevron, which has a market value of $232.9 billion, has climbed 10 percent this year to $119.76.

Comedian Ian Cognito died during a stand-up act in which he joked about dying on stage and then fell silent while the audience continued laughing, thinking it was a joke.

"Imagine if I died in front of you lot here," Cognito, 60, joked on stage during his set Thursday. Andrew Bird, who runs the Lone Wolf Comedy Club in Bicester England, told the BBC: "Everyone in the crowd, me included, thought he was joking. Even when I walked on stage and touched his arm I was expecting him to say 'boo'."

Audience members were mortified when they learned that had been chuckling at a man dying. "We came out feeling really sick, we just sat there for five minutes watching him, laughing at him," said audience member John Ostojak. He added: "Only 10 minutes before he sat down he joked about having a stroke He said, 'Imagine having a stroke and waking up speaking Welsh?'"

Fellow comedians extended their sympathies on Twitter after hearing the news of Cognito's death, but commented that his demise was in some ways fitting.

“Died with his boots on. That’s commitment to comedy. I’ll never forget his kindness when I started out & how god damn funny he was,” said comedian Jimmy Carr.

Comedian Mark Steel said Cognito had "expired in his natural home" and was "a difficult awkward hilarious troubled brilliant sort, a proper comic."

Bird said that dying on stage would have been the way Cognito "would have wanted to go," adding: "Except he'd want more money and a bigger venue"

There is a comedic tradition of dying on stage. In 1984, comedian Tommy Cooper suffered a heart attack in the middle of his set on live television.His assistants and viewers back home thought he was making a joke as he slumped over and then writhed on the ground.

Cognito, whose real name was Paul Barbieri, had been performing since the mid-1980s. He won the Time Out Award for Stand-up Comedy in 1999 but never really hit the big time.

Acting Defense Secretary Patrick Shanahan told reporters Friday the Pentagon stands ready to dispatch more troops to the border region if President Trump follows through with his pledge to increase the military presence along the U.S.-Mexico boundary.

Trump said after touring a section of recently upgraded border fencing in Calexico, Calif., last week, “We're going to bring up some more military” to deal with what he said were more than 70,000 illegal migrants rushing the border.

Shanahan said the Pentagon has had conversations with the Department of Homeland Security but has yet to receive a formal request.

“It shouldn't come as a surprise that we'll provide more support to the border,” he said in response to a reporter’s question as he prepared to meet with German Defense Minister Ursula von der Leyen. “Our support is very elastic, and given the deterioration there at the border, you would expect that we would provide more support.” Shanahan said he anticipates the support will be similar to what the military has already provided with several thousand troops, barrier construction, transport, and surveillance.

Shanahan will meet with a planning team at the Pentagon over the weekend to prepare for the potential request, he said.

“It will follow up with where are we on barrier construction, where do we stand on troops deployed, and then in the areas we anticipate, what type of preliminary plans should we be doing prior to receiving a request for assistance,” he said.

Democrats have been highly critical of the deployment of active-duty troops to the border, and many have cited a leaked internal memo the Marine Corps commandant sent to the Navy secretary warning that unexpected expenses, such as hurricane damage and border operations, could force him to cancel routine training and degrade combat readiness.

But in Senate testimony this week, Gen. Robert Neller insisted his memo was being misconstrued. “To say that going to the border was degrading our readiness is not an accurate statement,” Neller told the Senate Armed Services Committee Tuesday.

Neller’s March 18 memo listed eight categories of unfunded and unexpected expenses. Hurricane recovery was at the top of the list, but a number of expenses were included, such as the raise for civilian employees, which was not in the budget.

“We have a shortfall of just under $300 million, of which the border mission is less than 2 percent,” Neller said. “So my intent was to just simply lay out for my boss what these were and ask for support in trying to figure out how we might fund them.”

Pressed by Sen. Elizabeth Warren, D-Mass., Neller conceded some Marines, who are not doing the jobs they would normally do, could see a small degradation in their unit readiness, but he said it depended on the unit.

“Some of the units have gone down there and they've done tasks that are more in line with their core mission. Like engineer units or MP units. Aviation units that were assigned to that early on have actually improved their readiness because they are able to fly certain profiles and things,” he testified.

Neller reports to his civilian boss, Navy Secretary Richard V. Spencer, who requested the memo and jumped to Neller’s defense at the hearing.

“The main stress that we were dealing with at the time, senator, was the hurricane, which was imposing the greatest cost on the Marine Corps," Spencer told Warren. "Five hundred men for a month at the southern border is $1.25 million. In my mind, is that affecting my readiness stress? No, it's not.”

Neller said so far border operations have cost the Marine Corps $6.2 million.
