House Majority Leader Steny Hoyer (D-MD) made a shocking revelation on the floor of the House Thursday, telling the chamber that someone from the Republican side had told Rep. Tony Cárdenas (D-CA) to “return to Puerto Rico.”

Hoyer called for civility in his floor remarks, and began by referencing the resolution the House passed rebuking Rep. Steve King‘s (R-IA) racist remarks.

“We have just been through a very difficult week, in which one of our members was — a review and disapproval was passed almost unanimously, I think, with just one vote opposed to it on our side,” Hoyer said.

Hoyer then revealed that “Unfortunately, at a height, I know, of a lot of emotion, one of our members, respected member of our caucus, Tony Cardenas, was met with — who is, by the way, from California — was met with a call from the other side of the aisle to return to Puerto Rico.”

“We ought to all be cognizant of the fact that we need to be civil to one another, we need to be polite to one another, even,” Hoyer continued.

Hoyer concluded by noting that while the two parties may disagree, “I would hope that we could refrain from any implications which have any undertones of prejudice or racism, or any kind of ‘ism’ that would diminish the character and integrity of one of our fellow members.”

Cardenas was among the delegation of 36 Democratic lawmakers who attended the Latino Victory Fund’s annual summit in Puerto Rico last weekend.

Trump attacked the delegation for going to Puerto Rico during the shutdown, but Cardenas defended the trip to the hurricane-ravaged territory, telling The Hill “We started planning this a year ago, and just because there’s a Trump shutdown it doesn’t mean that the world is going to stop. We appreciate and respect every single worker who’s being punished by Donald Trump. But at the same time, there’s over 3.2 million Puerto Rican American citizens on this island that deserve for us to continue to do our job.”
