Trump urges quick conclusion of Russia probe

President Donald Trump today responded to the appointment of a special counsel to investigate his campaign's ties with Russia by protesting his innocence and calling for the probe to conclude "quickly."

"A thorough investigation will confirm what we already know -- there was no collusion between my campaign and any foreign entity," Trump said in a tersely written statement.

"I look forward to this matter concluding quickly," Trump said, without directly commenting on the Justice Department's appointment of former head of the FBI Robert Mueller as a special investigator.
