James Comey, the FBI director who was fired last year by President Donald Trump, is urging voters to support Democrats in November’s midterm elections.

Comey says on Twitter that the “Republican Congress has proven incapable of fulfilling the Founders’ design that ‘Ambition must … counteract ambition.'” That refers to the need for Congress to provide checks and balances to presidential power.

Comey writes: “All who believe in this country’s values must vote for Democrats this fall. … History has its eyes on us.”

The former FBI director recently said he no longer considers himself a Republican.

This Republican Congress has proven incapable of fulfilling the Founders’ design that “Ambition must … counteract ambition.” All who believe in this country’s values must vote for Democrats this fall. Policy differences don’t matter right now. History has its eyes on us.

On Monday, after Trump’s press conference with Russian President Vladimir Putin, Comey tweeted, “This was the day an American president stood on foreign soil next to a murderous lying thug and refused to back his own country.”

This was the day an American president stood on foreign soil next to a murderous lying thug and refused to back his own country. Patriots need to stand up and reject the behavior of this president.

Having sold out our nation on an international stage, Mr. Trump will now explain it all to Sean Hannity and Tucker Carlson? I’m guessing RT and Sputnick were unavailable. He owes it to our nation to sit down with a serious journalist.
