A member of President Donald Trump's personal legal team argued that "there's no crime of collusion" after a foreign policy adviser to Trump's campaign pleaded guilty to FBI agents about his communications with Russian nationals.

"There's no crime of collusion," Jay Sekulow said on Good Morning America of George Papadopulos, who admitted to making false statements and material omissions in January to investigators probing Russian interference in the 2016 election.

ABC reports, that Papadopoulos had attempted to arrange a meeting between the Trump campaign and Russian officials.

When asked whether the president has ruled out firing special counsel Robert Mueller, Sekulow said, "The president has not indicated to me or to anyone else that I work with that he's had any intent on terminating Robert Mueller. You could only terminate a special counsel for cause and we just don't see any basis for cause."

Paul Manafort and Rick Gates, who served as Trump's campaign manager and deputy campaign manger respectively, were indicted on 12 charges Friday and surrendered to federal authorities on Monday.
