Wednesday at a town hall set to air on CNN later in the evening, President Barack Obama responded to Congress’ override of his veto of legislation that would allow families of the victims of the September 11, 2001 terror attacks to sue Saudi Arabia.

According to Obama, the veto was “a mistake” and he attributed Congress’ decision to what he called a political vote.

“I think it was a mistake, and I understand why it happened,” Obama said. “Obviously all of us still carry the scars and trauma of 9/11.”

He went on to call it a “dangerous precedent” as well.

“It’s a dangerous precedent and it’s an example why sometimes you have to do what’s hard,” Obama said. “And frankly I wish Congress here had done what’s hard. I didn’t expect it, because if you’re perceived as voting against 9/11 families right before an election, not surprisingly, that’s a vote for people to take. But it would have been the right thing to do.”
