Hartford -- U.S. Sen. Richard Blumenthal, D-Conn., is scheduled to announce a new legislative effort Monday morning that would amend Senate rules to compel all presidential cabinet nominees to release at least three years of tax returns.

In addition, Blumenthal is calling on president-elect Donald Trump to release copies of his federal tax returns in conjunction with his planned Dec. 15 explanation of how he plans to separate himself from his extensive business holdings.

“Trump enters the White House with unprecedented potential conflicts of interest resulting from his international business empire and holdings within the United States,” stated the release from Blumenthal’s office. “Without access to his tax returns, the American public has no way to verify that Trump has in fact fully severed ties from his business interests, including vast international holdings.”

In a press release about Monday’s 11 a.m. announcement at the Legislative Office Building, Blumenthal said that currently only select Senate committees have the authority to require nominees to produce tax returns, an oversight he said Democrats will seek to correct in the next session.
