WASHINGTON (AP) — Thirty-one days into the partial government shutdown, Democrats and Republicans appeared no closer to ending the impasse than when it began, with President Donald Trump lashing out at his opponents after they dismissed a plan he'd billed as a compromise.

Trump on Sunday branded House Speaker Nancy Pelosi a "radical" and said she was acting "irrationally." The president also tried to fend off criticism from the right, as conservatives accused him of embracing "amnesty" for immigrants in the country illegally.

Trump offered on Saturday to temporarily extend protections for young immigrants brought to the country illegally as children and those fleeing disaster zones in exchange for $5.7 billion for his border wall. But Democrats said the three-year proposal didn't go nearly far enough.

"No, Amnesty is not a part of my offer," Trump tweeted Sunday, noting that he'd offered temporary, three-year extensions — not permanent relief. But he added: "Amnesty will be used only on a much bigger deal, whether on immigration or something else."

The criticism from both sides underscored Trump's boxed in-position as he tries to win at least some Democratic buy-in without alienating his base.

With hundreds of thousands of federal workers set to face another federal pay period without paychecks, the issue passed to the Senate, where Majority Leader Mitch McConnell has agreed to bring Trump's proposal to the floor this week.
