Democratic U.S. lawmakers introduced legislation on Tuesday that would bar the president and other top officials from accepting payments from foreign governments while in office, a measure clearly aimed at Republican presidential candidate Donald Trump.

The bill, which has no chance of passing the Republican-controlled U.S. House of Representatives as the Nov. 5 election approaches, is aimed at tightening enforcement of the Constitution’s “Emoluments Clause.”

House Oversight Committee Democrats released a report in January that found businesses tied to former President Trump received at least $7.8 million in foreign payments from 20 countries during his four years in the White House.

“For centuries, the President and other high-ranking government officials strictly respected the Foreign and Domestic Emoluments Clauses. Sadly, President Trump’s brazen acceptance of illegal foreign payments and benefits showed the need for clear rules enforcing the Constitution’s preeminent anti-corruption provisions,” said Senator Richard Blumenthal, who introduced the bill with Representative Jamie Raskin.
