According to the private and confidential memo, Brock plans to defeat Trump “through impeachment,” using American Bridge, his liberal super PAC, as the main vehicle to do so.

“No other progressive organization has the resources and assets that American Bridge has amassed over the past several election cycles to hold Trump, his administration, and the politicians accountable,” the 44-page confidential memo states.

“Only Bridge stands ready with staff already hired, Trump’s web of business ties mapped out, and a massive video archive at our fingertips.”

“The right will bolster Trump aggressively and deceptively. The campaign to stop him must be nonstop. At American Bridge, it has already begun.”

Brock’s group claims to have more than 20,000 hours of video, 289 candidate research books, and the largest available archive of Trump research in the Democratic Party.
