Republican operative David Bossie thinks the White House should worry about what Democrats have in store.

As House Democrats launch a massive investigation into President Trump, Bossie, Trump's former deputy campaign chair, warned Tuesday that it's pretty clear that "we are headed to impeachment." Bossie did say the White House is assembling a "killer team" to fight those charges, but right now, "we're not ready," he tells ABC News.

When Democrats flipped the House in November, they immediately made it clear they'd investigate Trump's campaign and administration. That probe officially launched last week as House Judiciary Chair Jerrold Nadler (D-N.Y.) requested documents from 81 people and entities tied to Trump. House Speaker Nancy Pelosi (D-Calif.), though, said Tuesday that impeachment is "just not worth it." Nadler also told The New York Times that "impeachment is a decision to be made further down the road."

Still, Bossie is convinced that charges against Trump are "potentially coming," he told ABC News' The Investigation podcast. He also said he "believe[s]" the White House is "in the process of getting ready" for the charges, saying it may not be a "slow roll" between the investigation's conclusion and an impeachment trial. Bossie then added that he doesn't think these swirling investigations are upending Trump's leadership skills, and even suggested the president "has the potential to benefit from all of this" if Democrats get "overzealous" with their prosecution.
