Washington( CNN) President Donald Trump fired off a series of tweets on Sunday lashing out at the special counseling investigation led by former FBI Director Robert Mueller.

Trump's statement comes after a week in which the President's former lawyer, Michael Cohen, permitted the release of a recording he made between himself and then-candidate Trump talking about a potential pay to a model who claims she had an affair with Trump. Cohen also claimed Trump knew about a 2016 session involving his campaign and a group of Russians who were expected to provide dirt on Hillary Clinton.

“There is No Collusion! The Robert Mueller Rigged Witch Hunt, headed now by 17( increased from 13, including an Obama White House lawyer) Angry Democrat, was started by a fraudulent Dossier, paid for by Crooked Hillary and the DNC. Therefore, the Witch Hunt is an illegal Scam! ” Trump tweeted Sunday.
