Eight days before President Trump was sworn in, hackers breached traffic and security cameras around Washington, D.C. The cameras were part of the security setup for the inauguration and were being monitored at an FBI command center.
There are 187 cameras in the city -- monitoring everything from the White House to the Capitol to the inaugural parade route -- and about 70 percent of them had been commandeered.
Chris Caruso is leading the investigation for the Secret Service.
