WASHINGTON (AP) — Bipartisan legislation introduced in the House on Wednesday would require presidents and vice presidents to publicly disclose tax returns before, during and after their time in the White House as Congress makes an election-year push to curb foreign influence in American politics.

The proposal, led by the unusual pairing of Republican Rep. James Comer and progressive Democratic Rep. Katie Porter, is the latest effort to bolster congressional oversight of presidential ethics as both parties grapple with congressional investigations into their leading candidates for the White House.

“We both agreed that this was going to be a bill about the future and about restoring trust in government,” Porter told The Associated Press on Wednesday. “It’s not a bill about any past president.”

Democrats on Tuesday introduced rival legislation that would enforce the Constitution’s ban on emoluments, which prohibits a president from accepting foreign gifts and money without the permission of Congress. Proponents of that proposal say Republican Donald Trump brazenly ignored the clause while president as foreign government officials flocked to his various hotels and properties.
