Mayor Marty Walsh’s immigration stance has taken him into the spotlight again. Walsh appeared on Comedy Central’s “The Daily Show With Trevor Noah’’ Tuesday night.

Walsh, a vocal critic of President Trump’s travel ban, chatted with Noah about the immigration crisis that’s roiling the country.

Noah asked Walsh about why the mayor wants to help undocumented immigrants stay in the country.

Walsh said that with 28 percent of Bostonians being immigrants and 43 percent of residents being first-generation Americans, it’s the proper stance.

“As the mayor of a city that’s primarily a first-generation immigrant city, I think it’s important for me to stand up, and there’s other great mayors around the country that have stood up as well,’’ Walsh said.

Walsh told Noah that he saw youths paying attention during the presidential election and noticed that a lot were afraid after the election.

If Washington “truly wants to deal with fixing immigration,’’ Walsh said, then Republicans and Democrats need to come together on reform.

“That’s the way you do it, not by putting out threats,’’ Walsh said, rebuking Trump’s threats to withhold federal funding from sanctuary cities.

If you’re going to take money away from a major city like Boston, and other cities across America, you’re doing damage to the economy and you’re hurting the economy,’’ Walsh said.

According to Walsh, Boston receives about $500 million in federal funding: $100 million goes toward schools, $25 million to public safety, $25 million to other programs, and $280 million goes toward housing.

Noah praised Walsh’s stance, calling it a tough position to be in because Walsh hails from one of the few US cities to be struck by terrorism.

“Many people can speak, but very few people actually come from a city where they have been the victims of a terror attack,’’ Noah said.
