"This is a scandal far greater in scope and magnitude than Watergate and those who were involved in and knew about this spying operation should be subject to criminal prosecution," Trump said. "In a stronger period of time in our country, this crime would have been punishable by death."

Trump added: "In addition, reparations should be paid to those in our country who have been damaged by this."

Former chief investigator of the Trump-Russia probe for the House Intelligence Committee under then-Rep. Devin Nunes, R-Calif., Kash Patel, said the filing "definitively shows that the Hillary Clinton campaign directly funded and ordered its lawyers at Perkins Coie to orchestrate a criminal enterprise to fabricate a connection between President Trump and Russia." 

"Per Durham, this arrangement was put in motion in July of 2016, meaning the Hillary Clinton campaign and her lawyers masterminded the most intricate and coordinated conspiracy against Trump when he was both a candidate and later President of the United States while simultaneously perpetuating the bogus Steele Dossier hoax," Patel told Fox News, adding that the lawyers worked to "infiltrate" Trump Tower and White House servers. 

The anti-Trump dossier, authored by ex-British intelligence officer Christopher Steele, commissioned by opposition research firm Fusion GPS, was funded by the Democratic National Committee and Hillary Clinton's campaign through Elia's law firm, Perkins Coie. 

Patel added that Sussmann relayed the "false narrative" to U.S. government agencies "in the hopes of having them launch investigations of President Trump." 

Sussmann's indictment is the second prosecution to come out of Durham's probe.
