The president launched his latest tweetstorm Friday morning, during which he once again blasted the mainstream media, described the probes of his administration as a "witch hunt" and seemingly confirmed that he is now under investigation. Who is Trump referring to?
ABC News reported on Friday that Rosenstein recently discussed the possibility that he may have to recuse from any involvement in the special counsel probe, given his role in writing the Comey memo, with Associate Attorney General Rachel Brand. Because Attorney General Jeff Sessions recused himself from the probe, it was Rosenstein who appointed Mueller to the job. The Justice Department had no comment on Trump's tweet Friday.
His tweets come as Mr Trump marks two years since announcing his plan to run for president. In that case, Rosenstein could be called as a witness. Though, somewhat ironically, that report relied on unnamed sources.More news: 'Wonder Woman' breaks box office records with $100.5 million opening

The Washington Post reported this week that Mueller is investigating whether Trump attempted to obstruct justice when he suggested Comey drop an FBI investigation into Michael Flynn, Trump's former national security adviser, as well as when he fired Comey.
It's a shift in the FBI investigation, which previously focused on Russian hacking during the election, possible coordination between the Trump campaign and Russian officials, and possible financial crimes by Trump associates.
"Why is that Hillary Clinton's family and Dems dealings with Russian Federation are not looked at, but my non-dealings are?" he asked.
I can see why his Vice President Mike Pence has chose to lawyer up. Pence's office confirmed he had retained Richard Cullen, a former Virginia attorney general and USA attorney for the Eastern District of Virginia, to assist "in responding to inquiries" from Mueller.
"There's still no evidence of obstruction, and current and former leaders in the intelligence community have repeatedly said there's been no effort to impede the investigation in any way", she said in a statement.
But Mr Comey also testified that to his knowledge the president had not tried to stop the Russian Federation investigation. If Trump is confirming the existence of an investigation targeting him, it would represent an extraordinary development less than five months into his presidency.
Rosenstein earlier this month confirmed he had the ultimate authority to hire or fire Mueller, but said he has been given a wide berth to conduct the probe.
