Mike Pompeo, who President Trump tapped Tuesday to replace Rex Tillerson as secretary of state, has an extraordinary resume. He graduated at the top of his class at West Point. He served as a tank officer in Europe. He went to Harvard Law School.
He was a corporate lawyer who launched a successful aerospace business. He got elected to Congress as a Tea Party Republican from Kansas in 2010. For more than a year, he's run the CIA.
However, he's never been a diplomat, either by profession or temperament.
"Pompeo is very much a hardliner on issues of national security, broadly," said Ian Bremmer, head of the Eurasia Group, which analyzes global politics. "He's smart, but he's also quite bombastic, and that plays well with Trump. But that doesn't necessarily support a balanced national security policy."
Pompeo recently declared that the U.S. would not soften its stance on North Korea ahead of planned talks between North Korean leader Kim Jong Un and President Trump.
"Make no mistake about it," Pompeo said on Fox News Sunday. "While these negotiations are going on, there will be no concessions made."
Pompeo has previously suggested he favors regime change in North Korea, though, he said in December, "I've learned the art of nuance in my 10 months" at the CIA. "So suffice it to say, I hope that diplomatic and economic pressure will help resolve this in a way that doesn't require a military outcome that I know nobody is excited about."
Pompeo has also been a leading critic of the nuclear deal with Iran. He took the unusual step of sending a warning letter to Qasem Soleimani, the head of Iran's Al-Quds force, which operates in Iraq and elsewhere in the Middle East.
"I sent a note to Qasem Soleimani because he indicated that forces under his control might threaten the U.S.," Pompeo said during a conference last year at the Ronald Reagan Presidential Library outside Los Angeles. "He refused to open the letter. It didn't break my heart."
Chemistry with the president
"With Mike, we've had a very good chemistry from the beginning," President Trump told reporters Tuesday, before leaving for California. Trump said that Gina Haspel, the deputy director at the CIA, would be replacing Pompeo.
One of Pompeo's strengths is his strong personal bond with the president.
Here's how Pompeo described the intelligence briefing he provides most mornings at the White House:
"We have a half-hour, 40 minutes every day. He asks lots of hard questions as any good intelligence consumer would. He's very engaged."
Leon Panetta, who served as a CIA director under President Obama, says he and Pompeo speak regularly about the job they've shared.
"God bless Mike Pompeo for having the ability to sit down with the president and have the president listen. I was a little worried about that," said Panetta, who appeared alongside Pompeo at the event held at the Reagan Library. "But if Mike is doing that, and the president is engaged, that is extremely important to the president being able to do the job."
However, The Washington Post recently challenged this scenario, reporting that the face-to-face presidential briefings tended to play down or avoid matters relating to Russia, which might upset Trump.
"Russia-related intelligence that might draw Trump's ire is in some cases included only in the written assessment and not raised orally, said a former senior intelligence official familiar with the matter," the newspaper reported.
Pompeo's supporters say he'll be a much better fit as secretary of state than Rex Tillerson, who often seemed out of sync with the president.
Pompeo is likely to have far more credibility as the president's surrogate when he speaks to foreign leaders.
Hard power vs. soft power
"Donald Trump is really comfortable with a guy in uniform, a guy who is the spymaster," said Danielle Pletka of the American Enterprise Institute.
But there will be challenges, she said, because the president appears to prefer the hard power of the military.
"I suspect [Trump] has much less of an affinity for the soft power that diplomacy represents," she said. "So will Mike Pompeo's good rapport with the president be able to withstand the soft power vibe of the State Department? Great question. Don't know."
After winning election to Congress in 2010, Pompeo has risen rapidly as an aggressive partisan.
Before he joined the Trump administration, he was perhaps best known as an outspoken critic of Hillary Clinton and the way she handled the attack on the U.S. diplomatic compound in Benghazi, Libya, in 2012, when she was secretary of state. The U.S. ambassador and three security personnel were killed in the attack.
"Why don't you fire someone?" Pompeo said at the 2015 congressional hearing. "How come no one has been held accountable to date?"
"In the absence of finding dereliction or breach of duty, there could not be immediate action taken," Clinton said.
"The folks in Kansas don't think that was accountability," Pompeo said.
On most issues, it's hard to find any daylight between Trump and Pompeo.
Pompeo even says the president's less-than-diplomatic tweets — directed at rivals — have worked to the CIA's benefit.
"Our adversaries respond to the tweets in ways that were helpful to us — to understand command and control issues, who's listening to what messages, how those messages are resonating around the world," Pompeo said.
