Key members of Congress are weighing dramatic changes to the embattled Secret Service, including moving it out of the Homeland Security Department and breaking up its mission.

The proposals come as lawmakers assess how to improve the agency after a series of scandals, including a White House break-in by a man with a knife last month. The agency’s director, Julia Pierson, resigned amid the controversy, but lawmakers are promising they'll continue their focus once Congress reconvenes after the Nov. 4 midterm elections.

In the latest development, The Washington Post reported yesterday on evidence implicating a White House advance team member in a prostitution scandal involving Secret Service agents in Colombia in 2012. White House officials have denied involvement by anyone on their team, but the Post story said White House officials were informed at the time.
