Republicans are expressing fury over allegations Hillary Clinton operatives paid a contractor to spy on former President Donald Trump during his 2016 campaign and into his presidency.

They are calling it the “biggest crime in U.S. history” while demanding “a total clean out of the political class in Washington.”

Taking to social media, Republican lawmakers offered critical reactions, with Trump calling the scandal “worse than Watergate,” after Special Counsel John Durham filed a motion in federal court in Washington D.C. on Friday alleging Hillary Clinton’s political allies paid a contractor to spy on the former president — both as a candidate, and as president.

“Durham’s report shows that the Trump campaign and White House were illegally spied on, paid for by the Clinton campaign,” wrote Ronna McDaniel, chair of the Republican National Committee (RNC).

 “There needs to be accountability,” she added.

“Hillary Clinton is the MOST corrupt politician in American history,” wrote Rep. Ronny Jackson (R-TX). “How she spied on President Trump is CRIMINAL!” 

“This is just the tip of the iceberg too. The full truth of Hillary’s crimes have yet to be revealed,” he added. “LOCK HER UP!”

“The corrupt Clinton campaign paid a team to spy on their political opponent,” wrote Rep. Claudia Tenney (R-NY).

“Congressional investigations are coming,” she added. “The truth will come out.”

“Evidence is out that Hillary Clinton and her campaign allegedly paid tech companies to manufacture a false narrative that Donald Trump was linked with Russia,” wrote Tennessee Republican Senator Marsha Blackburn.

“It’s time for @HillaryClinton to answer serious questions about her ties to the Russia hoax,” she added.

“Hillary Clinton must immediately be held accountable for her involvement in the biggest criminal political corruption story of our lifetime,” wrote House Republican Conference Chair Rep. Elise Stefanik.

This is the biggest criminal political corruption story of our lifetime,” she added. “America deserves accountability for these crimes.”

“This is bigger than Watergate,” wrote Rep. Mike Johnson of Louisiana.

“Yesterday it was revealed that the Clinton Campaign paid a tech company to infiltrate Trump Tower/White House servers and drum up the now-debunked phony Russian collusion hoax that the media ran with,” wrote GOP Rep. Jim Banks (R-Ind.).

“What crime are you guilty of if you lose a presidential race and respond by illegally spying on the White House to undermine the duly-elected president?” he asked.
