Republicans and Democrats, including Reps. Alexandria Ocasio-Cortez and Nancy Mace, are canceling events and taking other security precautions.

The assassination of conservative activist Charlie Kirk is sending shock waves through Capitol Hill, with lawmakers on both sides of the aisle expressing fears for their own safety and taking greater security precautions following a summer of political violence.

Members are beefing up their security, moving public events indoors or canceling them altogether. One is even vowing to carry firearms.

Rep. Alexandria Ocasio-Cortez, D-N.Y., the progressive star who has faced numerous death threats over the years, said Thursday she had postponed two public events planned for this weekend in North Carolina, including a rally in Raleigh set for Sunday.
