Jerry DeLemus, a co-chair of Veterans for Trump in New Hampshire, is expected to plead guilty for his role in the 2014 militia standoff at the Bundy family’s Nevada ranch, the Las Vegas Review-Journal reported on Tuesday.

In a court filing, Chief U.S. District Judge Gloria Navarro said DeLemus has indicated he would change his plea on August 23 after signing a plea agreement.

DeLemus, who had been listed as an alternate delegate for Donald Trump to the RNC weeks after his indictment, faces nine federal charges, including conspiracy to commit a crime against the country and threatening a federal law enforcement officer.

The news makes DeLemus, who was pegged by federal officials as a “gunman and midlevel organizer” for his role in the armed standoff over grazing rights, the first of 19 defendants to make a deal with prosecutors, according to the Review-Journal.

The 2014 standoff in Bunkerville, Nevada became a flashpoint for anti-government activists in their decades-long battle with the federal government over grazing rights on public lands. DeLemus resurfaced earlier this year when he traveled to rural Oregon to lend his support to rancher Cliven Bundy’s sons, who were leading an armed takeover of an Oregon wildlife refuge.

The Trump campaign did not immediately respond to a request for comment from TPM.
