Arizona Republican Senator, Jeff Flake blasted the United States President, Donald Trump in a blistering speech delivered on the floor of the Senate on Tuesday.

Flake said he cannot be “complicit or silent” to what the current administration is up to because he had “children and grandchildren to answer to.”. He went on to reveal that he will not run for re-election after his current term ends in early 2019.

In a passionate address to fellow senators, and TV cameras, Flake lamented the White House’s “reckless, outrageous and undignified behavior ” which he said was “dangerous to a democracy”. Flake, who is Trump’s party member, went on to accuse the US President of having a “disregard for truth and decency”.

He warned about the changes in the political climate, which he referred to as “the new normal” and said his colleagues must stop pretending those changes are normal because they are not. He proceeded to implore them not to embrace the “new normal.”

Following Flake’s speech, White House Press Secretary Sarah Huckabee Sanders called the speech “petty” and also suggested his departure from the Senate was probably for the best “based on the lack of support that he has from the people of Arizona”.
