President Donald Trump's lawyer told The New York Times the president "has no concerns" about what his former aides will tell Justice Department special counsel Robert Mueller.

"The president has no concerns in terms of any impact, as to what happens to them, on his campaign or on the White House,” Cobb, said in an interview Thursday for the Times’ podcast, “The New Washington.”

Mueller is leading the probe into Russian meddling in the 2016 presidential election and possible collusion between the Trump campaign and the Kremlin. He has also focused his investigation into obstruction of justice by the president, who might have tried to obstruct the probe.

Trump's former campaign manager Paul Manafort and former national security adviser Michael Flynn are key targets in Mueller's investigation. Manafort's home in Virginia was raided in July and people close to him have been issued subpoenas. Mueller has been investigating Manafort on allegations that he violated tax laws and laundered money. Sources say he has been told to expect an indicment.

A federal grand jury in Washington on Friday approved the first charges in Mueller’s investigation, but the charges are still sealed.

"[Trump] likes and respects Mr. Manafort and appreciates the work he did for him during the three months he was with the campaign. He likes General Flynn personally, but understands that they have their own path with the special counsel," Cobb said. "I think he would be sad for them, as a friend and a former colleague, if the process results in punishment or indictments. But to the extent that that happens, that's beyond his control."
