The head of the House Homeland Security panel says the nation is lucky that the security breach at a White House state dinner didn't result in a "night of horror."
Bennie Thompson spoke before the start of a hearing by his panel into just how Tareq and Michaele Salahi were able to get into the dinner for the prime minister of India last week without an invitation.
Secret Service director Mark Sullivan -- the only witness at the hearing -- told the panel that mistakes were made. And he added, "In our line of work, we cannot afford even one mistake." But he said he's confident President Barack Obama was never at risk.
The committee chair says the panel still needs to talk to the Salahis, and to White House social secretary Desiree Rogers. All three were invited to appear today, but declined. Thompson had said last night that if the Salahis didn't show up, the committee was ready to move ahead with subpoenas.
