Pueblo, Colorado - After Congresswoman Lauren Boebert was endorsed by the Colorado Republican Party, a number of state Republicans are calling for the chairman of the group to resign.

In a statement released on Tuesday, Richard Holtorf, one of Boebert's rivals in the congressional primary race for Colorado's 4th District, accused CRP Chairman Dave Williams of violating bylaws that prevent the group or any officer from endorsing a candidate in a contested primary election.

"Williams continued to abuse his office as State GOP Chair by trying to bypass all Republican delegates and voters in eastern Colorado with an endorsement concocted by his own hand," Holtorf argued.

"This is not only unethical, but possibly illegal."

Holtorf's criticism came after the CRP announced their endorsement of Boebert on Monday after she swept the competition at a recent GOP assembly, where she earned 41% of party delegates up for grabs and secured her place on election ballots.

The CRP also criticized candidate Deborah Flora for "boot licking fake journalists who only help Democrats" after she shared a post about a reporter with The Colorado Sun being ejected from the GOP assembly for her "unfair" reporting.

Officials with the Huerfano County Republican Party sent a letter directly to Williams on Tuesday, where they condemned his "blatant suppression of a free press" and accused him of credentialing delegates long before the GOP assembly took place, which created an opportunity for "fraud and election abuse" to occur.

"This body now calls on Chairman Williams to immediately resign his position," the letter stated.

Williams, a far-right MAGA Republican, has been head of the state's GOP since last year and is currently running in a separate primary to represent the state's 5th District.

Both he and Boebert have also been endorsed by former President Donald Trump in their respective races.

In a Truth Social post on Tuesday, Trump praised Williams and claimed he is "under Fake News assault because he is doing such a strong job as an advocate for MAGA."

The CRP's endorsement of Boebert was met with heavy criticism on social media, with many calling the group out for picking a single candidate while there are several others in the race.

As Trump and other Republicans have been pushing forward a plan to install more MAGA Republicans and Trump allies into positions of power, especially as the former president fights for re-election, Williams has an invested interest in propping up candidates like Boebert.

In response to Holtorf's call for him to resign, Williams told Colorado Politics that he doesn't plan on going anywhere.

"If Holtorf wishes to stand against the near-unanimous majority of convention delegates and President Trump, then he's definitely going to lose in June," Williams said.
