The House unanimously voted Friday to pass a bill bolstering Secret Service protection for major presidential and vice presidential candidates, a move that comes in the wake of two apparent assassination attempts targeting GOP presidential nominee Donald Trump.

Lawmakers are scrambling to ensure that the U.S. Secret Service has enough money and resources to keep the nation's presidential candidates safe amid repeated threats of violence. It's unclear, though, how much they can do with only weeks before the election, or if additional dollars would make an immediate difference.

In a rare unanimous bipartisan vote in the House, the body passed legislation that would increase Secret Service protection for the two presidential nominees and their running mates.
