U.S. President Donald Trump on Monday dismissed the testimonies of former acting Attorney General Sally Yates and former Director of National Intelligence James Clapper, reports The Hill.

Yates, speaking before a Senate Judiciary panel, said she warned the White House that former national security adviser Michael Flynn created a "compromise situation" and could have been "blackmailed."

Yates was talking about the revelation that Flynn misled Vice President Mike Pence about the true content of a December call with Russian Ambassador Sergey Kislyak.

Clapper, for his part, said there is “no evidence” of collusion between Trump’s presidential campaign and Russia.

Trump tweeted that Yates’ testimony was “old news”.

“Sally Yates made the fake media extremely unhappy today --- she said nothing but old news!” he wrote.

“Director Clapper reiterated what everybody, including the fake media already knows- there is "no evidence" of collusion w/ Russia and Trump,” added Trump.

The president also stressed that there was no collusion between his campaign staff and Russia.

“The Russia-Trump collusion story is a total hoax, when will this taxpayer funded charade end?” he tweeted.

Trump asked for Flynn’s resignation in February, following the reports that he misled Pence about his conversations with the Russian Ambassador.

As for the alleged relations between, Trump has accepted intelligence reports concluding that Russia engaged in cyber attacks during the November presidential election, but has repeatedly lambasted as “fake news” any suggestion that he or his staff had connections to Russia.

Russia denies the allegations altogether.
