America hasn’t faced a potential coup d’etat since the 1930s when bankers plotted to overthrow President Franklin D. Roosevelt. But after Donald Trump’s election Tuesday, some people on Twitter accused FBI Director James Comey of staging a coup.

Comey, a former Republican, issued a letter to Congress on Oct. 28, announcing the FBI’s discovery of more emails from Hillary Clinton’s team. Many Clinton supporters said Comey's letter would cripple Clinton's chances of swaying Independent and Republican voters. Just a few days after the initial announcement, Comey issued another letter clearing Clinton and saying the new batch of emails contained no new or actionable evidence. He said the new emails wouldn’t lead to any charges against the presidential candidate or the Clinton Foundation.

Despite’s Comey’s clearance, the initial letter fed into the Trump campaign's anti-Clinton rhetoric. While speaking at a campaign rally in Michigan on Sunday, Trump cited the FBI’s investigation to further his claims about “the system” being rigged to keep power in the hands of the government.

“Hillary Clinton is guilty. She knows it. The FBI knows it. The people know it, and now it’s up to the American people to deliver justice at the ballot box on Nov. 8,” Trump said.

California Sen. Dianne Feinstein said in a statement Sunday that Comey’s letter “unfairly hurt the campaign of one candidate and changed the tenor of this election,” and many people on social media appear to agree with her statement. Some Twitter users called Comey’s letter and the FBI’s investigation on the Clinton Foundation a coup d’etat, or an attempt to rig the election in Trump’s favor.
