Former FBI Director James Comey is urging "all who believe in this country's values" to vote for Democrats in the upcoming midterm elections.

In a tweet on Tuesday evening, Comey called the Republican-held Congress "incapable of fulfilling the Founders' design."

"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," he wrote.

The elections that Comey refers to are the midterm polls which will take place in the middle of Republican President Donald Trump's term. All 435 seats in the United States House of Representatives and 35 of the 100 seats in the United States Senate will be contested.

Comey who has been a registered Republican for most of his adult life, sent out this tweet after U.S. President Donald Trump’s performance at the joint press conference with Russian President Vladimir Putin was seen as supporting Russia’s version of events with respect to election meddling in the run-up to the 2016 Presidential race. Speaking next to Russian President Vladimir Putin, Trump repeatedly rejected the conclusions of the U.S. intelligence agencies and failed to publicly condemn Russia for allegedly meddling in the 2016 election.

“They said they think it’s Russia,” Trump said of the U.S. intelligence community, before adding: “I have President Putin … he’s just said it’s not Russia. I will say this, I don’t see any reason why it would be.”

Comey who was fired by Trump had immediately tweeted after the press conference, saying "This was the day an American president stood on foreign soil next to a murderous lying thug and refused to back his own country.”

The former FBI director has been vocal about his frustration with the Republican Party before, and in April he said he could no longer "be associated with it."

"The Republican Party has left me and many others. I need no better evidence than their new website -- which I think is 'Lyin Comey,' maybe? -- attacking me. I just think they've lost their way, and I can't be associated with it," Comey told ABC News' "Start Here" podcast at the time.

He continued in his interview with ABC News: "I see the Republican Party, as near as I can tell, reflects now entirely Donald Trump's values." "It doesn't reflect values at all. It's transactional, it's ego-driven, it's in service to his ego," he added.
