President Trump, in a Saturday morning tweetstorm, responded to the mounting questions over his ties to Russia by accusing Obama of wiretapping him at Trump Tower just before the November election.

The outburst follows several days of stories raising questions about meetings between members of the Trump campaign and Russian officials, particularly two previously undisclosed meetings between now Attorney General Jeff Sessions and Russian ambassador Sergei Kislyak.

The tweet blasts began at 6:26 a.m. from the Winter White House at Mar-a-Lago in Florida when Trump raised the Sessions issue by noting that the first meeting between the senator from Alabama and the Russian ambassador was set up by the Obama administration as part of an education program.

Eight minutes later, he raised the charge of illegal surveillance by the Obama administration: "Terrible! Just found out that Obama had my "wires tapped" in Trump Tower just before the victory. Nothing found. This is McCarthyism!"

Then: "Is it legal for a sitting President to be "wire tapping" a race for president prior to an election? Turned down by court earlier. A NEW LOW!"

And: "I'd bet a good lawyer could make a great case out of the fact that President Obama was tapping my phones in October, just prior to Election!"

Sessions has recused himself from any Trump-Russia investigation after the Justice Department acknowledged he had spoken twice with the Russian ambassador last year and had failed to disclose the contacts during his Senate confirmation process.

Sessions said he had not tried to mislead anyone but could have been more careful in his answers. He planned to file amended testimony on Monday, a Justice Department spokesman said.

The president first responded to the Sessions issue obliquely on Friday, by taking a swing at Senate Minority Leader Charles Schumer, noting he had previously met with Russian President Vladimir Putin. Trump then demanded an investigation of close ties between Schumer, House Minority Leader Nancy Pelosi and Russia and "lying about it."

He called Schumer, who has demanded Sessions' resignation, a "total hypocrite."
