WASHINGTON, D.C. — House Speaker Nancy Pelosi warned President Donald Trump on Thursday that a future Democratic president could declare a national emergency to achieve an agenda, such as gun control policy.
Responding to the president’s announcement that he will declare a national emergency related to the U.S. southern border, Pelosi maintained that “Democratic presidents can declare emergencies as well. So the precedent that the president is setting here is something that should be met with great unease and dismay by the Republicans.”
Speaker Pelosi told reporters at her weekly press conference, “You want to talk about a national emergency? Let’s talk about today, the one-year anniversary of another manifestation of the epidemic of gun violence in America. That’s a national emergency. Why don’t you declare that emergency, Mr. President?”
