Twelve Republican senators, including Mississippi's Roger Wicker, sided with Democrats Thursday and voted to block President Donald Trump's declaration of an emergency on the southwest border. Sen. Roger Wicker of Mississippi: "I strongly support (Trump's) plan to build walls on our southern border, but an emergency declaration (is) the wrong approach. The president already has almost $6 billion available that can be used to build border walls. I am concerned about the precedent an emergency declaration sets, which might empower a future liberal president to declare emergencies to enact gun control, address 'climate emergencies' or even tear down the wall we are building today."
