‘How dare you’: Trump pummeled for ‘marrying’ gun reform to his ‘racist’ immigration laws

President Donald Trump promised action after a pair of mass shootings in El Paso and Dayton, but he also threatened to tie any gun safety measures to immigration legislation.

The president will address the nation Monday morning to discuss the massacres, but he previewed possible action in a pair of tweets.

"We cannot let those killed in El Paso, Texas, and Dayton, Ohio, die in vain," Trump tweeted. "Likewise for those so seriously wounded. We can never forget them, and those many who came before them. Republicans and Democrats must come together and get strong background checks, perhaps marrying this legislation with desperately needed immigration reform. We must have something good, if not GREAT, come out of these two tragic events!"

The El Paso gunman posted an anti-immigrant manifesto that echoed language used by Trump, and other social media users reacted to his suggestion with furious outrage.
