President Trump launched new attacks on his predecessor and Democrats on Sunday, suggesting Barack Obama also has shady Russian ties.

At 6:40 a.m., Trump insinuated that Obama acted improperly in March 2012 when the then-president told Russian President Dmitry Medvedev that the US would have more “more flexibility” in talks about a missile defense treaty after November elections.

The “more flexibility” remark was picked up on a hot mic that Obama and Medvedev apparently did not know was on.

“Who was it that secretly said to Russian President, `Tell Vladimir that after the election I’ll have more flexibility,’” tweeted Trump, under fire for his administration’s ties to Moscow.

That tweet came after a 6:32 a.m. missive that suggested Democrats didn’t want to help the FBI investigate cyberattacks now linked to Russia.

“Is it true the DNC would not allow the FBI access to check server or other equipment after learning it was hacked? Can that be possible?” Trump tweeted.

The president’s Sunday morning tweets came 23 ½ hours after he made sensational – and uncorroborated – claims that Obama had his phones at Trump Tower tapped during the 2016 campaign.

Obama’s spokesman denied the former president ordered any such covert action against Trump.

Democrats and some Republicans roundly criticized Trump for making such a wild, unsubstantiated claim.

Congressman Ted Lieu (D-Calif.) comically took Trump’s side and said maybe he was put under surveillance – for good reason.

“Mr. President: If there was a wiretap at Trump Tower, that means a fed judge found probable cause of crime which means you are in deep sh–,” Lieu tweeted.
