"Mueller is setting up a dragnet of obstruction, financial questions and every aspect of Trump's life and his associates lives", said former House Speaker Newt Gingrich, who labeled it "very unsafe". In an earlier tweet, he called it a massive "witch hunt".
While most Republicans in Congress said little about Mr. Trump's criticism of Mueller, other supporters echoed the President's concerns. Comey, though, would not say whether he thought it constituted obstruction of justice, leaving that conclusion up to Special Counsel Robert Mueller.
"The investigation is the biggest scandal since Watergate and it's everbody's hope that justice at last can be delivered", Trump said back in October.
"We may have our differences, but we do well, in times like these, to remember that everyone who serves in our nation's capital is here because, above all, they love our country", Trump said. "Nice", Trump tweeted, according to the Guardian.
The president has long vehemently denied any collusion with Moscow, either by himself or his associates.
On Wednesday night, the latest twist in the story was revealed to be that the president is now under investigation for possible obstruction of justice.
Allies have even floated the idea that Mueller may be fired.
He also raised questions about Clinton's family and, quote - "Dems dealing with Russian Federation".
Shortly afterward, Trump wrote: "Crooked H destroyed phones with hammer, "bleached" emails, and had husband meet with AG days before she was cleared- and they talk about obstruction?"
Five people spoke to the Post on the condition of anonymity, because "they were not authorized to discuss the matter publicly".
