Prior to Thursday's meme, The Briefing's last tweet had been on November 7, one day before Trump's surprise election win.
In an earlier tweet, he called it a massive "witch hunt".
After a seven hour rest from Twitter, Trump then fired up again at his election rival.
The New York Times had alsoreported the investigation was now looking into if Trump associates laundered from Russian Federation during presidential campaigns.
"Crooked H destroyed phones w/ hammer, "bleached" emails, & had husband meet w/AG days before she was cleared- & they talk about obstruction?" He's tweeting about being under investigation despite a building full of people, including lawyers, who don't want him to do that because, well, duh.
Mueller is also reportedly investigating whether Trump associates committed financial crimes.
Once Comey was sacked, the Department of Justice appointed Mueller as special counsel to act as an independent investigator.
Except that Trump's tweet, technically speaking, refers to his own "non-dealings" rather than possible actions of his campaign and administration.
Attorney General Jeff Sessions, Trump's son-in-law Jared Kushner and campaign advisor Paul Manafort have also been implicated. The FBI later concluded that Clinton was not aware of the deletions.
Comey had testified that Lynch, as President Obama's attorney general, directed him on how to describe the Federal Bureau of Investigation probe into Clinton's email practices.
It was closed days later after concluding all the emails were duplicates of ones previously scrutinised.
For the record Mr. Comey, destruction of evidence is actually a federal crime and it was actually admitted to in actual FBI testimony, but only after you, Mr. Comey, chose to pass out immunity deals to Hillary's staff "like candy".
Despite winning the popular vote by several million, Clinton lost the election thanks to narrow defeats in the swing states of Michigan, Pennsylvania and Wisconsin.

California Congressman Moves to Impeach President Trump
I am not calling for Trump's impeachment because I disagree with every part of his unsafe and hateful agenda, although I do. A motion to table would be the likely outcome of that, but it would constitute the first impeachment-related vote.
