Scoop: Biden plans order to limit southern border crossings by end of month

Why it matters: We're told there's a fierce debate internally about the legality and politics of a Trump-like lockdown. But Biden, briefed on polls of rising voter anger, wants a dramatic step.

Between the lines: The provision Biden is eyeing would restrict the ability of immigrants to claim asylum, and doesn't require congressional approval, Axios reported in February.

• Biden would use authority in Section 212(f) of the Immigration and Nationality Act, which gives the president broad leeway to block entry of certain immigrants if it would be "detrimental" to U.S. national interests.
• He'd be taking a page from former President Trump, who has repeatedly leaned on that section.

Zoom in: "We're examining whether or not I have that power," Biden told Univision's Enrique Acevedo in an interview taped last week that aired Tuesday night.

• "Some are suggesting that I should just go ahead and try it," Biden said. "And if I get shut down by the court, I get shut down by the court."
• Biden said there's "no guarantee" he has the power to take action on the border without legislation from Congress.
• But he plans to lean in.
