Clinton leads Trump in the popular vote, 61,694,263 to 60,961,967, Cook officials said, with 20,000 votes from Montgomery County, Md., pushing her over the 1 million mark.

Trump won the White House via the Electoral College a week ago, while the former secretary of State is now the fifth nominee in American history to win the popular vote but lose the presidency.

Online petitions with millions of signatures have called on electors to vote for Clinton when they vote in December, citing her lead in the popular vote.

Those are highly unlikely to go anywhere, as electors would be unwilling to ignore precedent or vote against their state's pick.

"In my lifetime, I have seen two elections where the winner of the general election did not win the popular vote," Boxer said in a statement.

"The Electoral College is an outdated, undemocratic system that does not reflect our modern society, and it needs to change immediately."

Boxer's legislation is unlikely to pass, however.

Even if it is approved by Congress, it would need to be approved by three-fourths of the states within seven years before it would take effect.

The president-elect has flipped on his feelings regarding the Electoral College, calling it "genius" on Tuesday after labeling it a "disaster for democracy" in 2012. Trump said if the election were based on popular vote, he would have campaigned differently and beaten Clinton that way, too.
