Lawmakers in both the House and Senate are launching a sprawling multicommittee investigation into the Secret Service’s security failures that resulted in the assassination attempt against former President Donald Trump at a rally in Pennsylvania over the weekend. 

The Senate Homeland Security Committee announced it will launch a bipartisan investigation looking into the series of security failures that allowed a shooter to scale a building hundreds of feet away from a stage where Trump was standing, where the former president was grazed by a bullet, one person was killed, and at least two others were injured.
