The President mentioned Clinton by name on Twitter 28 times in the month of August - the most often since October of 2016 - just before he won election as President.
What was going on in August? The President's former campaign manager Paul Manafort was on trial, as he was ultimately found guilty on eight counts of tax and bank fraud.
After Labor Day on the way to the elections - the President went almost totally silent on Twitter about both the Mueller investigation and Clinton - until this week.
On Wednesday, the President re-tweeted a graphic calling for "trials for treason" against Mueller, Clinton, former President Obama and others - including current Deputy Attorney General Rod Rosenstein.
Asked by the New York Post on Wednesday why he sent out that graphic including Rosenstein, the President made clear a familiar line of displeasure.
"He should have never picked a special counsel," Mr. Trump said in the newspaper's Oval Office interview.
Last week, the New York Times reported that the President wanted to order the Justice Department to prosecute Clinton, along with former FBI Director James Comey, but that Mr. Trump's White Counsel refused to follow through, reportedly arguing it was an abuse of presidential powers.
