Mueller to focus on possible Trump-Russia collusion: report

Special counsel Robert Mueller will in the coming months focus on whether the Trump campaign colluded with Russia, Bloomberg reported Tuesday.

A person familiar with the investigation told Bloomberg that Mueller's team is looking to wrap up the portion of the probe focused on collusion by the fall and hand down any possible collusion-related charges in that time frame.

The special counsel's office declined to comment to Bloomberg.

At least 13 people tied to President Trump have been revealed over the course of the probe to have been in contact with Russians, according to the outlet.

Former Trump campaign adviser Roger Stone was the latest to reveal that a Russian man offered damaging information on 2016 Democratic presidential nominee Hillary Clinton in exchange for $2 million.

Stone claims that the man was acting as an FBI informant. The man, Henry Greenberg, confirmed the meeting but denied that he was working for the FBI, and records do not indicate that he was working in that role.

Trump has repeatedly attacked Mueller's probe into possible collusion between Russia and the Trump campaign in the 2016 presidential race, calling it a "witch hunt." Trump has maintained that no collusion took place.

Mueller charged 13 Russian nationals and three Russian groups with election interference earlier this year.

He has also brought charges against several Trump associates, including former campaign chairman Paul Manafort, but those charges are largely unrelated to election interference.
