Mueller is in the midst of a 15-month investigation of Russian meddling in the 2016 USA presidential election, Trump campaign ties to Russia and whether Trump, as president, obstructed justice by trying to thwart the investigation.
The president has denied knowledge of the meeting at his Trump Tower campaign headquarters in NY in the face of news accounts saying his former personal attorney, Michael Cohen, is prepared to tell special counsel Robert Mueller that he heard Trump's son tell his father in advance about the meeting.
Sen. Rubio drew the ire of conservatives and Trump supporters in July when he said that the Federal Bureau of Investigation did nothing wrong by spying on Trump's campaign advisor, Carter Page.
"Well, the question is, how would it be illegal?"
That Sekulow had misstated the origin of the July 2017 statement provided to The New York Times and attributed to Donald Trump Jr. became clear earlier this year, in a leaked letter from Trump's legal team to Mueller's office.
Mr. Trump's attorney Jay Sekulow defended the legality of the meeting Sunday on ABC's "This Week," saying no law or statute has been violated. While originally Trump, a Republican, said the meeting was about adoptions, on Sunday he said on Twitter that it was about getting information on his election opponent, Democrat Hillary Clinton. "I had a lot of information to process".
However, Sekulow said that Trump may ignore his attorneys' advice.
He added that just because he got it wrong, it doesn't mean there was wrongdoing.
Sekulow, repeating the recent mantra of Trump's legal team and of the president himself, said there "has been no evidence at this point of any type of collusion by the president".
The misdirection came amid a series of searing tweets sent from Trump's New Jersey golf club.
Trump has stepped up his public attacks on the Mueller probe since the first trial to arise from it began last week in Alexandria, Virginia, involving former Trump campaign chairman Paul Manafort.
Throughout that October, Trump cited emails disseminated by WikiLeaks on a near daily basis ― even though he began receiving briefings in August 2016 that told him that USA intelligence agencies had determined those emails had been stolen by Russian spies.
"The president can't distinguish between any allegations of conspiracy against his campaign and the broader problem of Russian Federation continuing to interfere in our elections", Schiff said on CBS's "Face the Nation". It's all about Article II, ' he said.
Trump has reportedly told several of his advisers and friends that he's anxious the investigation could destroy the lives of "innocent and decent people", namely his son.
Trump's admission that his son's 2016 Russian meeting was to get information on Clinton runs counter to the narrative he has previously pushed about the meeting.
But legal experts have pointed out several possible criminal charges, including conspiracy against the United States and aiding and abetting a conspiracy.
