3 GOP senators say they'll vote to block Trump's emergency declaration

Several other Republican senators are undecided on how they'll vote on the House resolution, but have previously expressed concerns about Trump's use of emergency powers.

• Sen. Marco Rubio (R-Fla.): "We have a crisis at our southern border, but no crisis justifies violating the Constitution. Today's national emergency is border security. But a future president may use this exact same tactic to impose the Green New Deal."
• Sen. Rand Paul (R-Ky.): I’m not in favor of operating government by national emergency. ... We have a government that has a constitution that has a division of power, and revenue raising and spending power was given to Congress.”
• Sen. Pat Toomey (R-Pa.): “I never thought that was a good idea. I still don’t. My view is that this is better to be resolved through the legislative process.”
• Sen. Lamar Alexander: "The president has made a strong case for increased border security, but declaring a national emergency is unnecessary, unwise and inconsistent with the U.S. Constitution."

• Sen. Ben Sasse: "We absolutely have a crisis at the border, but as a Constitutional conservative I don’t want a future Democratic President unilaterally rewriting gun laws or climate policy. If we get used to presidents just declaring an emergency any time they can’t get what they want from Congress, it will be almost impossible to go back to a Constitutional system of checks and balances."
• Sen. Mike Lee: "Congress has been ceding far too much power to the executive branch for decades. We should use this moment as an opportunity to start taking that power back."
