Sen. Snowe: Secret Service scandal probably not a 'first-time event'

Six agents so far have resigned in the wake of the scandal involving at least 20 prostitutes brought to a hotel in Colombia that the Secret Service was scouting ahead of a state visit by Obama.

Multiple Republicans who are on the House and Senate committees investigating the allegations have expressed concern that a "culture" exists at the agency, which allows such behavior to flourish. 

"We have to get to the source of this problem and whether or not a culture existed," Snowe said. 

She went on to advocate more women joining the Secret Service.

"The fact that it's 90 percent dominated by males indicates that we have to do further outreach, frankly, encourage women to join this service. Certainly it could change the overall atmosphere and culture, and certainly would be a healthier representation for the agency itself and society."
