Celebrities react to Attorney General William Barr's redacted Mueller report

Stars didn't take kindly to Attorney General William Barr and his release of a redacted report from Special Counsel Robert Mueller.

On Thursday, Barr claimed in a contentious press conference that Mueller found no evidence of collusion between members of Donald Trump's presidential campaign and the Russians during the 2016 election.

"After nearly two years of investigation, thousands of subpoenas, and hundreds of warrants and witness interviews, the Special Counsel confirmed that the Russian government-sponsored efforts to illegally interfere with the 2016 presidential election but did not find that the Trump campaign or other Americans colluded in those schemes," Barr said, adding that Americans "should be grateful" for the findings.
