The move was announced Tuesday morning, as the president also confirmed that Rex Tillerson, who held the position for about one year, has been ousted.
Pompeo thanked Trump for the opportunity in a statement, writing: “If confirmed, I look forward to guiding the world’s finest diplomatic corps in formulating and executing the President’s foreign policy.”
Here’s what we know about the 54-year-old set to assume one of the most powerful positions in the Trump administration.
Who is Mike Pompeo?
Pompeo took on the role of CIA director in January 2017, but prior to that he served as a Republican member for Kansas in the U.S. House of Representatives.
He is a retired army officer and a graduate of the U.S. Military Academy. He also attended Harvard Law School.

Relationship with Trump
Pompeo has been a trusted member of Trump’s team, and two are generally known to have similar political views.
The CIA director routinely briefs the president on intelligence matters concerning North Korea, and has insisted that the U.S. will not make any concessions in talks with Pyongyang.
Like Trump, Pompeo is known for his stern criticism of Iran. He has pushed for the 2015 Iran nuclear deal, which curbed Tehran’s nuclear program in exchange for sanctions relief, to be scrapped.
Pompeo has also downplayed the extent of Russian involvement in the 2016 U.S. election, criticizing former president Barack Obama for not being tougher on Russia.

Pompeo defended use of torture
Also in line with the president, Pompeo has insisted that the notorious Guantanamo Bay prison is “critical to national security” and should remain open.
He has also defended the CIA’s use of torture tactics. In a 2014 statement made to Senate, he insisted programs used under the George W. Bush administration were “within the law.”
“These men and women are not torturers, they are patriots. The programs being used were within the law, within the constitution,” he said at the time, according to the Star-Telegram.

Reaction to Mike Pompeo’s new position
Trump’s announcement garnered praise from within his party Tuesday, with many senators and members of Congress praising Pompeo has a strong leader.
“Mike Pompeo is an excellent choice to lead the State Department and represent the United States around the world,” Florida Senator Marco Rubio tweeted.
But one Democratic congresswoman cautioned that Pompeo isn’t the right person for the job.
Democratic Leader Nancy Pelosi issued a statement warning that Trump’s quick firing of officials is hurting the country’s credibility overseas.
“Whenever Tillerson’s successor goes into meetings with foreign leaders, his credibility will be diminished as someone who could be here today and gone tomorrow,” she wrote. “Continuity in our diplomatic personnel and policies are vital for championing American security, values, and interests.”
