New York City Mayor Bill de Blasio met with President-elect Donald Trump Wednesday morning at Trump Tower to discuss the "concerns and needs of all New Yorkers," De Blasio said in an afternoon press conference. The meeting, which lasted just over an hour, touched on Trump's proposed deregulation of Wall Street, his proposed ban on Muslim immigration, and his plan to deport millions of undocumented immigrants.De Blasio, a Democrat, said he told Trump he was "very concerned" about Trump's "exclusionary polices toward Muslims," adding that "there are 900 Muslim members of the NYPD protecting all of us." He also decried Trump's "hurtful" rhetoric, especially the president-elect's decision to appoint Steve Bannon as a chief White House advisor, after Bannon's long track record publishing racist and sexist content as the head of Breitbart News. "I made it very clear my deep concerns about Mr. Bannon," de Blasio said.De Blasio has been an outspoken critic of Trump and his policies, encouraging protesters to continue demonstration outside Trump Tower, and stating that New York City would resist Trump's promised deportations. De Blasio has gone so far as to suggest destroying databases containing information on undocumented immigrants who obtained city identification cards. On Wednesday he did not elaborate on the suggestion of purging the databases. "I will talk about the IDNYC database in the coming days," he promised.—Kelly Weill
