US President Donald Trump accused Democrats on Monday of fabricating allegations of presidential election interference against Russia and creating more “fake news.”

His tweet came just as Federal Bureau of Investigation and National Security Agency chiefs were to speak to Congress on what ties Trump may have with Russia and his shocking claim that he was wiretapped by his predecessor, Barack Obama.

Former national intelligence director “James Clapper and others stated that there is no evidence Potus colluded with Russia. This story is FAKE NEWS and everyone knows it!” Trump said on Twitter.

“The Democrats made up and pushed the Russian story as an excuse for running a terrible campaign. Big advantage in Electoral College & lost!” he added.

Trump also tweeted that the “real story” is the leaking of classified information.

The House Intelligence Committee will hear from FBI Director James Comey on whether US officials believe Russia tried to bolster Trump’s chances in the election and if there were any connections between Moscow and Trump’s campaign aides.

Comey has been invited to testify along with NSA director Michael Rogers.

Trump and his entourage’s possible ties with Russian President Vladimir Putin have been the subject of much speculation since before he was elected on November 8.

US intelligence agencies in January took the extraordinary step of stating publicly that they had concluded that hackers working for Russia broke into the email accounts of senior Democrats and released embarrassing ones with the aim of helping Trump defeat Hillary Clinton.

Even since then, the question of whether Trump and company were or are somehow in cahoots with Russia has dominated the national conversation.

A congressional panel so far has found no evidence that Trump’s campaign colluded with Russia, its chairman said Sunday.

Based on “everything I have up to this morning — no evidence of collusion,” by Trump’s team and Moscow, Representative Devin Nunes, chairman of the House Intelligence Committee, told Fox News.

Moscow has denied involvement in the hacks, and Trump has denounced the tumult over alleged Russia connections as a “total witch hunt.”
