The Electoral College meets Monday to formally elect the new president amidst growing debate about its role and whether it should even exist.

Progressive groups are planning protests at state capitols all over the country, which is where the electors will cast their votes. “The electors should follow the will of the people,” said activist Daniel Brezenoff in a statement. “Trump lost the popular vote by a historic margin and he should lose on Dec. 19 at the Electoral College.” Brezenoff’s Change.org petition to that effect has collected nearly 5 million signatures.
