Fox News senior judicial analyst Judge Andrew Napolitano joined the "Fox & Friends" co-hosts Tuesday to weigh in on what will likely happen if the Democrats capture the House in the midterm elections.

He explained that a Democrat-controlled House would mean that Rep. Nancy Pelosi (D-Calif.) will be Speaker and several anti-Trump lawmakers would take over as committee chairs, including Rep. Maxine Waters (D-Calif.) on the House Financial Services Committee, Rep. Elijah Cummings (D-Md.) on the House Oversight Committee, Rep. Adam Schiff (D-Calif.) on the House Intelligence Committee and Rep. Jerrold Nadler (D-N.Y.) on the House Judiciary Committee.

He said that some -- or all -- of those committees will likely open investigations into President Trump and his administration.

He pointed out that Nadler has already suggested he would open a "shadow investigation" of Special Counsel Robert Mueller's Russia probe, to determine if Trump fired former FBI Director James Comey for an improper purpose and, if so, if that was an impeachable offense.

"They want to be able to lay out on national television whatever Bob Mueller has acquired that he keeps secret, as the law requires," Napolitano said.

He noted that Nadler has also floated a possible investigation into Supreme Court Justice Brett Kavanaugh, to probe if he lied under oath during his confirmation hearings.

"They want to use the impeachment power to vindicate their view of government," Napolitano said.

He said the House Oversight Committee will look into how much Trump and his family members earn when foreign diplomats stay in Trump-managed hotels in New York City and Washington, D.C.

"Why are they doing that? That would be an opportunity for them to look at his income tax returns," Napolitano explained.
