Republican Rep. Darrell Issa, who chairs the House Oversight Committee, is hinting at a broader investigation of President Obama's Secret Service detail after revelations that 11 agents were sent home from Colombia for alleged misconduct involving prostitutes.
Issa of California told CBS This Morning that lawmakers will "look over the shoulder" of the Secret Service as it conducts its own internal investigation of the alleged incident that occurred ahead of the Summit of the Americas in Colombia, which President Obama attended.
