Rep. Jerrold Nadler, D-N.Y., is trying a rarely used tactic to try to force House Republicans to consider President Donald Trump’s potential conflicts of interest.

Nadler introduced a resolution of inquiry asking the Justice Department to provide information about Trump and his associates’ possible ties to Russia, conflicts of interests, and ethics violations.

If the House Judiciary Committee does not schedule the resolution for markup within 14 days, then it can be brought to the House floor. Should the resolution pass, it would compel the Justice Department to provide any information it has on Trump and his associates, including material from criminal and counterintelligence investigations, the New York Daily News reported.

“Donald Trump has refused to step away from his business interests in any meaningful way,” Nadler said in a statement. “His foreign entanglements are likely unconstitutional, he has repeatedly refused to disclose his financial assets, and he is clouded by the specter of Russian intervention in the election and his administration.”

Nadler, a member of the Judiciary Committee, criticized committee Chairman Rep. Bob Goodlatte and House Speaker Paul. D. Ryan for ignoring Democrats’ concerns.
