While NBC, which is owned by Comcast (CMCSA), sees entertainment value in the choice of host, not everyone is excited. A number of Hispanic groups plan to hold a “Dump Trump” protest on Wednesday outside SNL’s studios at 30 Rockefeller Plaza in Manhattan, the New York Times reports. They are calling on SNL executive producer Lorne Michaels to drop Trump—and they are armed with petitions bearing hundreds of thousands of signatures.

The groups, which are pro-immigration, point to Trump’s offensive comments about Mexican immigrants as a basis for why NBC ought not promote the candidate. On Monday, the Congressional Hispanic Caucus (CHC) issued a formal statement of opposition to the hosting gig, calling on NBC to “disinvite Mr. Trump from hosting Saturday Night Live because racism is not funny.”

Trump last hosted SNL in 2004. Earlier this week, he held a book signing event at his Trump Tower hotel in Manhattan, not far from where today’s protests will take place.
