Indiana Senator Joe Donnelly is joining two other Democrats in supporting Mike Pompeo’s confirmation as the next secretary of state.

The Indiana Democrat joins other centrist democrats Heidi Heitkamp of North Dakota and Joe Manchin of West Virginia in crossing party lines to back the current CIA Director.

Donnelly says in a statement that he came to the decision after having a meeting with Pompeo, saying he belives he’ll give President Trump “an honest assessment of critical issues” like North Korea, Russia, Syria, and ISIS.

Donnelly’s support comes as President Trump is attacking Democrats for their pushback against Pompeo’s nomination.

Trump says on Twitter Monday: “Hard to believe Obstructionists May vote against Mike Pompeo for Secretary of State. The Dems will not approve hundreds of good people, including the Ambassador to Germany. They are maxing out the time on approval process for all, never happened before. Need more Republicans!”

Pompeo’s nomination faces serious opposition from key Democrats and at least one Republican. The Senate Foreign Relations Committee may not have enough votes to recommend him for confirmation.

The full Senate is still expected to consider Pompeo’s nomination later this week. But the rebuke from the panel would be the first time in years a nominee for the position did not receive a favorable vote.
