Trump on Thursday lashed out at the investigators driving the Russian Federation investigation as "very bad and conflicted people", responding angrily to reports that the special counsel is looking into whether Trump obstructed justice.
The tweets potentially could put the president into deeper legal peril.
The Post reported that the interviews represent a widening of the probe to include looking into whether the President obstructed justice in suggesting to his former FBI Director James Comey that Comey drop the investigation into Michael Flynn, Trump's former national security adviser, as well as for his firing of Comey.
The Special Counsel appointed to oversee the probe into possible ties between Donald Trump's campaign and Russian Federation is investigating the business dealings of Jared Kushner, the President's son-in-law and a senior White House adviser, according to reports.
Mueller, a former FBI Director appointed by George W. Bush, was hired to lead the investigation by Deputy Attorney General Rod Rosenstein on May 17.
In December 2016, Kushner met with Russian ambassador Sergey Kislyak in New York City.
Mueller is a former head of the Federal Bureau of Investigation.
Trump fired Comey last month, saying "this Russian Federation thing" was on his mind when he made the decision to oust the nation's top law enforcement official while Comey was leading the FBI's probe into Russia's meddling.
"After the appointment of our former partner Robert Mueller as special counsel, we advised Mr. Kushner to obtain the independent advice of a lawyer with appropriate experience as to whether he should continue with us as his counsel", Gorelick said in a statement Sunday to The Times.
"I think he's weighing that option", he said of Trump. Comey testified that the member of his leadership team said that although it was true at the moment that Trump was not under investigation, it was possible that could change. A Reuters report said the meeting could have concerned lifting USA sanctions against Russian Federation.
Himes says the notion the investigation has been going on too long "is just crazy" and "we're talking about the very core of our democracy here". Kushner's lawyers say he will cooperate with investigators.
USA TODAY previously reported that the FBI was investigating Kushner for his contact with Russian officials, but there was no word at that time that his financial dealings were part of the probe. Mueller's investigation now encompasses the president's firing of Comey, the Russian government's role during the election, whether members of the Trump campaign colluded with Russian officials and alleged financial crimes committed by Trump associates. The first time he told Trump was in his first meeting with the president before the inauguration on January 6.
