A group of House Democrats has proposed legislation that would impose a series of penalties against foreigners who try to interfere in U.S. federal elections, the latest shot fired in the fight over whether Russia improperly tried to tip the election to President-elect Trump.

Rep. Eliot Engel, D-N.Y., and more than a dozen Democrats proposed the Protect American Democracy Act on Tuesday. The aim of the bill is to “expose and deter unlawful and subversive foreign interference in elections for Federal office.”
