California will ¡°imminently¡± challenge President Donald Trump¡¯s declaration of a national emergency to obtain funds for a U.S.-Mexico border wall, state Attorney General Xavier Becerra said on Sunday.

¡°Definitely and imminently,¡± Becerra told ABC¡¯s ¡°This Week¡± program when asked whether and when California would sue the Trump administration in federal court. Other states controlled by Democrats are expected to join the effort.

¡°We are prepared, we knew something like this might happen. And with our sister state partners, we are ready to go,¡± he said.
