"I'm sure they are tricked up, because, you know, they liked to catch people: 'Gee, was the weather sunny or was it rainy?"
It isn't clear now whether if, when Trump submits his written answers to the special counsel's office, that will end the matter or whether Mueller might still want to hear from the president in person.
Trump has always been dismissive of the Russian Federation investigation and, while this admission means he is cooperating with Mueller, he continued to dismiss the legitimacy of the probe.
The source would not explicitly say whether the President answered those questions other than to say that there are "responses" to all of the questions that were asked. "I wrote the answers", he said. He said then that the legal team was still unwilling to answer any questions concerning obstruction of justice by the president.
Trump's latest cabinet reshuffles and Twitter rants also appeared to reflect a growing concern over the probe.
Despite Trump's insistence Friday that he's "very happy" with how things are going, his frustrations with the ongoing probe have been evident everywhere from his overheated Twitter feed this week to his private grousing that the special counsel may target his family.
"The inner workings of the Mueller investigation are a total mess", Trump tweeted Thursday as part of a series of morning posts. They are a disgrace to our Nation and don't.care how many lives the (sic) ruin.
The president continued to maintain his innocence while launching a fresh round of attacks on the probe, saying "there should have never been any Mueller investigation" and claiming it was a waste of millions of dollars.
While the special counsel was publicly quiet in the run-up to last week's midterm elections, his investigation has suddenly returned to the forefront of Washington conversation and cable news chyrons.
Among those contacts were London-based professor Joseph Mifsud, who told him the Russians had "dirt" on Trump's Democratic presidential rival Hillary Clinton in the form of "thousands of emails".
For months, Trump has told confidants he fears that Donald Trump Jr., perhaps inadvertently, broke the law by being untruthful with investigators in the aftermath of a June 2016 Trump Tower meeting with a Kremlin-connected lawyer, according to one Republicans close to the White House.
Whitaker, who has been previously known to criticize the Mueller investigation, now oversees it. But anytime I even think about making changes, the FAKE NEWS MEDIA goes insane, always seeking to make us look as bad as possible!
