President Donald Trump vowed Wednesday to “never” repeal the Second Amendment after former Supreme Court Justice John Paul Stevens advocated for repeal in a recent New York Times op-ed.

“No way,” Trump wrote on Twitter. “We need more Republicans in 2018 and must ALWAYS hold the Supreme Court.”

THE SECOND AMENDMENT WILL NEVER BE REPEALED! As much as Democrats would like to see this happen, and despite the words yesterday of former Supreme Court Justice Stevens, NO WAY. We need more Republicans in 2018 and must ALWAYS hold the Supreme Court! — Donald J. Trump (@realDonaldTrump) March 28, 2018

Stevens, who retired from the Supreme Court in 2010, advocated for repeal in his op-ed, saying such action “would eliminate the only legal rule that protects sellers of firearms in the United States — unlike every other market in the world.”

“It would make our schoolchildren safer than they have been since 2008 and honor the memories of the many, indeed far too many, victims of recent gun violence.”

Stevens’ comments followed a gathering in Washington, DC led by students advocating for gun control who survived the February school shooting in Parkland, Florida. The gathering largely featured attendees who advocated full repeal of the Second Amendment.
