Former CIA Director John BrennanJohn Owen BrennanThe wisdom of Trump's lawyers, and the accountability that must follow Mueller's report Ex-CIA director blasts Trump over 'temper tantrums' Ex-CIA director: 'I don't have any doubt' Trump will pardon Manafort MORE suggested in an interview Tuesday that he "wouldn't be surprised" if special counsel Robert MuellerRobert Swan MuellerSasse: US should applaud choice of Mueller to lead Russia probe MORE hands down additional indictments at the end of the week, though he acknowledged he does not have inside knowledge.

Brennan said on MSNBC's "The Last Word" that he believes Mueller wants to hand over the threads of his investigation to prosecutors in the Southern District of New York and elsewhere.

"I wouldn't be surprised if, for example, this week on Friday, not knowing anything about it, but Friday is the day the grand jury indictments come down," Brennan said.

The former CIA chief, who served during the Obama administration and has since emerged as a fervent critic of President TrumpDonald John TrumpMueller report findings could be a 'good day' for Trump, Dem senator says Trump officials heading to China for trade talks next week Showdown looms over Mueller report MORE, added that Mueller may take into account that the following Friday, March 15, coincides with the Ides of March.

"I don't think Robert Mueller will want to have that dramatic flair of the Ides of March when he is going to be delivering what I think are going to be are his indictments, the final indictments, as well the report he gives to the attorney general," Brennan said.

He added that if Mueller indicts any members of the president's family, it would likely be his final act as special counsel.

Mueller has implicated six former Trump associates and dozens of Russians in his investigation into Russian interference in the 2016 election.

None of the charges have alleged conspiracy between the Trump campaign and Moscow, and the president has regularly decried Mueller's probe as a "witch hunt."
