The Dems are going to be hard-pressed to come up with enough votes for a veto override.
A Democrat attempt to block President Trump’s national emergency is virtually dead in the water after the White House issued a preemptive veto threat.
In a statement from the White House, the administration laid out why the declaration is a matter of national security, and said efforts to block it undermine the president’s ability to respond effectively to security threats.
This comes as a resolution makes its way through Congress, and is expected to pass the House and Senate Tuesday. This would be the first veto President Trump has issued since taking office.
