In his first State of the Union speech Tuesday night, President Donald Trump sought a more unifying tone after a year of divisive politics. A key part of that: He asked for a bill that would generate "at least" $1.5 trillion in infrastructure investment, up from the $1 trillion he'd previously talked about.

Rep. Bonnie Watson Coleman, a New Jersey Democrat who represents parts of Trenton and Princeton, said that "probably represents a fraction of what we need."

"I'm interested in making sure this is not a handout or a hand-down to private concerns," Coleman told WNYC. "I know that we need a robust infrastructure bill, and I know that both Democrats and Republicans are waiting to have that debate on what it should be."

A specific infrastructure concern the president didn't mention in his speech was the Gateway project to build a new train tunnel under the Hudson. But New York Republican Rep. Dan Donovan, who represents Staten Island and parts of Brooklyn, said he's not concerned. 

"I've met with the president, along with my colleagues from New Jersey," Donovan told WNYC. "He called us over, he listened to the plan, we explained to him how this is not just a benefit to New Jersey or New York, but it's a benefit to the entire nation."

"He laid out a generalization [on infrastructure]," Donovan added, "but when the details come out, many Americans will be working."

On immigration, however, the president largely veered to the right, doubling down on his plan to build a wall and limit family-reunification immigration in exchange for protecting the status of DACA recipients. 

"I think the president was playing to his base when he talked about the hard line he was going to take," Coleman said, "while at the same time, [his base] isn't particularly happy with his giving anybody a pathway to citizenship. They'd like him to probably deport them all."

"If the president wants to really settle this issue," Coleman said, "there has to be some compromise. So perhaps he was just laying out this sort of tough stance, so that he has a place to move from."

Across the aisle, Donovan expressed confidence about the immigration plan the president shared.

"We don't want to have another DACA problem ten years from now, so we have to secure our borders," said Donovan. "I think Bonnie's right in where some of these areas may need negotiation -- he put down a bottom line, and we'll negotiate from there. I mean, he is a negotiator. He's done that his entire life."

Coleman and Donovan spoke with WNYC's Richard Hake.
