Michigan Republican Mike Rogers says there's a "high probability" a chemical agent was deployed Tuesday in northern Syria.
Rogers spoke a day after the Obama administration disputed the Assad regime's claim that rebels had used such weapons in Aleppo.
Rogers tells "CBS This Morning" the U.S. knows "there has been some forensic evidence that at least small quantities" of chemical weapons may have been used. Rogers also says the United States has "lost the faith" of the opposition forces, adding, "This is the time to act. Don't wait until we have 5,000 dead."
