Sen. Tim Kaine, one of two Democrats on the Senate Foreign Relations Committee who voted for Mike Pompeo as CIA director, tells CNN that he has “serious doubts” about Pompeo’s nomination to State and his ability to be the top diplomat in the US.

Sen. Jeanne Shaheen, who also voted for Pompeo to CIA, said earlier she still has concerns with him going to State and he didn’t resolve them.

And GOP Senator Rand Paul has already said he would oppose Pompeo and reiterated those concerns during his line of questioning.

If all three vote no, Pompeo will not get a favorable recommendation from the committee because GOP only has a one-vote advantage.

Shaheen and Kaine said they hadn’t made a final decision yet.

Even with a negative vote in committee, GOP leaders could still move to advance the nomination and take it to the floor - something that is rarely done.

And GOP leaders would need to pick up at least one Democrat to jump ship and support Pompeo, given Paul’s opposition and John McCain’s absence.
