Jeff Sessions has again found himself as the target of Hillary Clinton’s liberal network, as an organization tied to the Democratic presidential candidate has filed an ethics complaint against the Alabama Senator.

The complaint aims at comments Sessions made during an October 15th campaign rally in New Hampshire, in which he said that the Trump’s opponents were working to hijack the results of the presidential race.

“They are attempting to rig this election,” he said. “They will not succeed.”

The American Democracy Legal Fund (ADLF) sent a letter on Monday to Georgia Senator Johnny Isakson, who chairs the Senate Select Committee on Ethics, urging members of the Senate to take “appropriate remedial action” against Sessions. They allege that Sessions’ claims were a violation of the legislative body’s code of conduct.

“Senator Sessions made baseless and irresponsible allegations that the 2016 presidential election is rigged, perpetuating unsubstantiated claims that threaten the stability of our election process and the safety of voters on Election Day,” ADLF wrote. “Such comments and behavior not only reflect negatively upon the Senate, but attempt to discredit our entire democratic system.”

ADLF is a well-known “dark money” group whose co-founders, Brad Woodhouse and David Brock, are also credited with the creation of pro-Clinton Super PAC Correct the Record. Brock was revealed by TIME Magazine to work directly with the Clinton campaign. Though coordinating with Super PACs is generally illegal under the law, TIME found that he legally exploited a loophole by operating Correct the Record exclusively online, rather than through print and broadcast.

Unsurprisingly, the Fund is no stranger to filing complaints that would benefit Clinton. During the Democratic Primary, they aggressively targeted Bernie Sanders and his allies.

In their letter against Sessions, ADLF acknowledged that the majority of voters are concerned about election rigging. They site a poll published by POLITICO last week, which found that 41 percent of voters believe the election could be “stolen” from Donald Trump. ADLF failed to mention Democratic members of the Senate like Harry Reid, who have accused Trump of colluding with Russia to steal the election.
