In Buffalo Wednesday just hours before Secret Service Director Julia Pierson resigned, Sen. Charles Schumer said there needs to be a "whole housecleaning" at the agency.
Schumer, a high-ranking Senate Democrat, said the Secret Service has always been known as the "gold standard of protection."
"After what we've seen in the last several months, they're not even the bronze standard. They're a lot worse than that. We need a gold standard. So there's got to be a really thorough thorough look into what went wrong, what they're going to do to correct it, and what is the matter with the Secret Service?," Schumer said.
"This isn't the first instance. It's one of several."
Schumer said he was shocked to learn that an intruder made it inside the White House. A knife-carrying Army veteran climbed over the White House fence September 19 and got deep inside the executive mansion.
Congressional support for Pierson eroded following her poorly received testimony Tuesday before the before the House Oversight and Government Reform Committee about the break-in.
Pierson had worked at the Secret Service for 30 years. Former special agent Joseph Clancy is taking over as acting Secret Service director.
