Robert Mueller did not find that the Trump campaign or its associates “conspired or coordinated” with Russia, the US Justice Department said.
Mueller, however, did not go so far as to exonerate Donald Trump of obstruction of justice.
The chairman of the House Judiciary Committee said a letter from the Justice Department describing special counsel Robert Mueller’s findings “does not conclude that the president committed a crime, it also does not exonerate him”.
The department sent the letter to Jerrold Nadler on Sunday afternoon.
Mr Nadler tweeted that the Justice Department “determined not to make a traditional prosecutorial judgment”.
