Pompeo, who previously ran the CIA, would replace Rex Tillerson, who was ousted from his top spot at the State Department by Trump earlier this month.
Trump offered praise for his new Secretary of State nominee during a speech at a GOP fundraiser dinner on Tuesday.
"Mike is going to do a great job,” Trump told the audience.
The abrupt replacement comes as the president prepares to meet with North Korean leader Kim Jong Un to negotiate the regime's weapons program.
Some Senate Democrats have voiced concerns about Pompeo, though Minority Leader Charles Schumer (D) has said he isn’t actively urgingDemocrats to oppose his nomination and a White House aide has said the administration expects enough Democrats to support him.
Sen. Rand Paul (R-Ky.) however has criticized Trump for appointing someone who has a favorable opinion of the Iraq War, refusing to rule out a possible filibuster.
Sen. Lindsey Graham (R-S.C.), however, has said he believes Pompeo has enough support to be confirmed.
