Man accused of trying to assassinate Trump 'armed to the teeth'

"Armed to the teeth." That's how Cole Tomas Allen, the man accused of trying to assassinate the US President, was described in court. Prosecutors shared a photo of the 31-year-old equipped with a knife and ammunition, which they say he took in a hotel room before heading to the White House correspondents' dinner. Meanwhile, questions remain over who fired the shot that struck a Secret Service agent when the suspect rushed the lobby of the event. Washington DC correspondent Todd Zwillich spoke to Lisa Owen.
