Former Senate Majority Leader Harry Reid condemned former FBI Director James Comey in a weekend interview, saying he didn’t do enough to curtail Russian meddling in the 2016 election.

Reid, a Democrat from Nevada, told radio host John Catsimatidis of 970 AM in New York that he sent a letter to Comey before the election urging him to look into Russia and reports that it was meddling in the election.

“I wrote a letter in August [2016] to the Director of the FBI Comey and said Russia is messing with our elections and you need to do something about that. And by October he had done nothing,” Reid said. “We now know he should have done something."

Reid said Comey didn’t get involved because he thought President Trump’s Democratic opponent, Hillary Clinton, was going to win. Reid has been a sharp critic of Comey since before the 2016 election and blamed the former FBI director for Clinton’s defeat. Comey was fired by Trump in 2017.

“Now the hindsight from his troops are that he didn’t do it because he thought Hillary would win the election. He therefore thought it would be too political for him to get involved,” Reid said.

Special counsel Robert Mueller submitted his final report on election meddling to Attorney General William Barr on Friday. Mueller was appointed within days of Comey’s firing, and Comey later told Congress he leaked memos between he and Trump to try to spur the creation a special counsel investigation.

Barr is expected to deliver a summary of the final report to Congress sometime Sunday afternoon.

During the interview, Reid warned that Russia will likely try to influence elections in the future, noting that the country is led by President Vladimir Putin, a former agent of the KGB.

“They’ve done it in the past. They are doing it as we speak in European countries. And they’re going to do it again in America,” Reid said.

Reid, 79, served in the Senate for 30 years, including as majority leader from 2007 to 2015. He was diagnosed with pancreatic cancer last year.
