Mike Pompeo, President Trump's nominee for Secretary of State, faces an uncertain vote as two Democrats on the Senate Foreign Relations Committee indicate they may not recommend his nomination to the full Senate.

Virginia Senator Tim Kaine and New Hampshire Senator Jeanne Shaheen have both indicated they harbor serious concerns over Pompeo's nomination, despite previously voting in favor of his appointment as CIA Director.

"I voted for him as CIA director and haven't had cause to regret that vote," Kaine toldCNN. "But I have serious doubts about whether he's the diplomat that we need right now."

Numerous Democrats on the committee raised concerns that Pompeo is a "war-hawk" in line with President Trump's recent appointment of John Bolton as National Security Advisor - an assertion Pompeo repeatedly denied.

"Every day at the forefront of our mind is how can we find solutions that achieve the American objective but avoid us having to put a single American in harm's way," Pompeo responded.

In addition to Kaine and Shaheen, Senator Rand Paul (R-KY) als0 indicated his opposition to Pompeo's nomination, expressing concern over his past support for the Iraq War. Paul also argued Pompeo's neoconservative-leanings are not in alignment with President Trump's "America First" agenda.

If all three vote against Pompeo, he will not have enough votes to win a favorable recommendation from the Foreign Relations Committee.

Under Senate rules, Majority Leader Mitch McConnell (R-KY) could still bring Pompeo's nomination to the full Senate for a vote despite the negative recommendation from the committee.

Such a move would be notable, as no cabinet nominee has been brought to the full Senate for a confirmation vote after a negative committee recommendation since 1945, when President Franklin Roosevelt appointed Henry Wallace to be Secretary of Commerce.

Due to Senator Paul's opposition and Arizona Senator John McCain's absence as he battles brain cancer, Pompeo would need to the support of at least one Democratic senator to be confirmed.

Three Democrats running for reelection in states carried by President Trump - Senators Joe Donnelly (D-IN), Heidi Heitkamp (D-ND), and Joe Manchin (D-WV) - all voted in favor of Pompeo's nomination as CIA Director.

Pompeo was confirmed as CIA Director by a vote of 66-32 vote, including 14 Democrats and one Independent who caucuses with the Democrats.
