Donald Trump continued to fume over the Russia investigation on Sunday, more than a year after special counsel Robert Mueller filed his report without recommending charges against the president but only three days after the justice department said it would drop its case against Michael Flynn, Trump’s first national security adviser.
“The biggest political crime in American history, by far!” the president wrote in a tweet accompanying a conservative talk show host’s claim that Barack Obama “used his last weeks in office to target incoming officials and sabotage the new administration”.
The tweet echoed previous messages retweeted by Trump, which earned rebukes for relaying conspiracy theories. On Sunday afternoon the president continued to send out a stream of tweets of memes and rightwing talking heads claiming an anti-Trump conspiracy. One tweet by Trump simply read: “OBAMAGATE!”
Trump fired Flynn, a retired general, in early 2017, for lying to Vice-President Mike Pence about conversations with the Russian ambassador regarding sanctions levied by the Obama administration in retaliation for interference in the 2016 election.
The US intelligence community has long held that such efforts were meant to tip the election towards Trump and away from Hillary Clinton, the Democratic nominee.
Flynn pleaded guilty to lying to the FBI – which Trump has acknowledged – and co-operated with Mueller, who was appointed to take over the investigation of Russian interference after Trump fired FBI director James Comey.
Mueller did not establish a criminal conspiracy but did lay out extensive links between Trump and Moscow and instances of possible obstruction of justice by the president.
Flynn sought to change his plea while awaiting sentencing and the president championed his case, floating a possible pardon. On Thursday, in an act that stunned the US media, attorney general William Barr said the justice department would drop the case entirely.
Trump and his supporters have loudly trumpeted the decision and across Saturday and Sunday the president unleashed a storm of retweets of supporters and conservative commentators attacking targets including Obama, Mueller, Comey and House intelligence committee chair Adam Schiff.
The talkshow host retweeted by the president, Buck Sexton, is a former CIA analyst who now hosts a show which he says “speaks truth to power, and cuts through the liberal nonsense coming from the mainstream media”.
In another message retweeted by the president, Sexton called former FBI deputy director Andrew McCabe – who Trump fired just short of retirement – “a dishonorable partisan scumbag who has done incalculable damage to the reputation of the FBI and should be sitting in a cell for lying under…
