Constitutional law professor Jonathan Turley joined Steve Doocy on "Fox & Friends" to weigh in on the "investigation onslaught" that Democrats plan to launch against the Trump White House now that they control the House.

Several prominent Democrats, including Senate Minority Leader Chuck Schumer (D-N.Y.), Rep. Jerrold Nadler (D-N.Y.) and Rep. Adam Schiff (D-Calif.), made appearances on Sunday shows and previewed how they plan to probe acting Attorney General Matthew Whitaker, Supreme Court Justice Brett Kavanaugh, President Trump himself and more.

Turley noted that Democrats campaigned on the promise that they would hit Trump and his administration with a "storm of subpoenas," and they appear primed to do so.

He said that even though Democrats only control one chamber of Congress, that's enough to bring individuals in to testify before congressional committees.

"There's an obvious interest in building a case for impeachment. It's just they don't really have the impeachment grounds," Turley said. "I just don't believe that they have enough right now to make out a compelling single article of impeachment."

He explained that the framers intended for impeachment to be a difficult legal standard, so lawmakers don't simply vote their political interests.

"Impeachment's not supposed to be a recreational exercise. It's not supposed to be something that you do to please your base. It's a very serious and disruptive and dysfunctional element to introduce into our system," Turley said.

He said the chances that Trump will be impeached are "virtually nil" at this point, but that won't stop Democrats from "throwing out a net" in search of any possible evidence of an impeachable offense.

"They don't have it right now. But when you look at the range and scope of the investigations, it's really breathtaking."
