California's existing gun control laws are under the microscope after 12 people were killed on Wednesday at a bar in Thousand Oaks, the New York Times reports.

The big picture: California already has some of the most restrictive gun control laws in the country, but governor-elect Gavin Newsom is considering passing "even tougher laws" following Wednesday's shooting. He said this week that he would have signed into law some gun measures that Gov. Jerry Brown vetoed in the past. At a press conference on Thursday, Newsom said the response "cannot just be excuses. The response sure as hell cannot be more guns," the Times reports. Newsom isn't the only one — House Democrats are also eyeing more aggressive gun control legislation in response to the Thousand Oaks shooting now that they have control of the House.
