WASHINGTON –Emboldened by special counsel Robert Mueller's finding that there was no collusion with Russia in the 2016 election, President Donald Trump and his Republican allies are going on offense over the issue as he heads into next year's campaign.

After Attorney General William Barr's summary of Mueller's conclusions exonerated Trump on the question of collusion, White House aides and Trump surrogates came out swinging in an effort to discredit Democratic critics, the media and the Justice Department over the now-completed 22-month probe.  

Trump described Mueller's probe as an "illegal take-down that failed" and urged "somebody" to look into the origins of the collusion allegations. On Thursday, he will have a chance to tout the outcome and press his criticisms when he heads to Michigan for one of the first rallies of his reelection campaign.
