Another Republican Senator has stepped forward to condemn Donald Trump, labelling the US President “dangerous to democracy” in a blistering take-down.

In a withering attack from the floor of the Senate, Jeff Flake, who represents Arizona, said it was “time for our complicity and accommodation to the unacceptable to end” and said Republicans would not “meekly accept such behaviour” if a Democrat was in the White House.

His tirade came hours after he joined fellow Republican Bob Corker in announcing he would not stand for office next year. Corker, too, unleashed a stinging rebuke earlier in the day – accusing Trump of “debasing” the US.

Damn. Jeff Flake: “When we remain silent… because we might alienate the base… we dishonor our principles & forsake our obligations.” pic.twitter.com/vE2V4HpOHZ

Flake is flaming Trump on the Senate floor: “Reckless, outrageous and undignified behaviour has become excused…as ‘telling it like it is'”
Flake, who has criticised the path that the Republican Party has taken under Trump, told The Arizona Republic in advance of his announcement that “there may not be a place for a Republican like me” in the current GOP.

Railing against the “appalling features of our current politics”, he told the Senate that lawmakers should “never regard as normal the regular and casual undermining of our democratic norms and ideals”.

“It is time for our complicity and our accommodation of the unacceptable to end,” he went on.

Flake published a book this year called Conscience of a Conservative: A Rejection of Destructive Politics and a Return to Principle, in which he takes on Trump and the GOP,  arguing that “conservatism is indeed in crisis”.

Corker, the US Senator who branded the White House an “adult daycare centre”, added today that the President has “great difficulty with the truth” and is “purposely breaking down relationships we have around the world that had been useful to our nation”.

“It’s amazing. Unfortunately world leaders are very aware that much of what he says is untrue,” Corker continued. “Certainly people here are because these things are provably untrue. They’re just factually incorrect and people know the difference.”
