One Colorado 12-year-old is spending his summer vacation helping Donald Trump get elected by running the campaign’s field office in one of the state’s most populous counties.

The Trump campaign’s field office in Jefferson County, which includes the greater Denver area, is largely run by Weston Imer, 12. While his mother, Laurel Imer, is listed as the office’s official field coordinator, she told KDVR that allowing her son to organize volunteers as co-chair of the county office has been a great learning experience.

“You have a responsibility to your children to teach them,” she told the station.

Imer said that last year he was bullied at school, but now he’s planning on a future White House run of his own.

“Watch for me – 2040,” he told KDVR. “Barron Trump, if you’re watching, in 2040 I’ll take you as my running mate.”

After news of Imer’s story spread, Guardian US reporter Ben Jacobs confirmed he was the same 12-year-old who reportedly made threatening calls to try to convince anti-Trump delegates to the RNC to back the New York city billionaire.

According to Jacobs’ reporting, Imer made calls identifying himself as speaking on behalf of both the Colorado GOP and the Trump campaign as he encouraged support for an effort to “free the delegates” after a contentious delegate selection process.
