With the Senate and House poised to vote on dueling bills to reopen the government this week, President Trump on Monday put the squeeze on Nancy Pelosi over her rejection of his latest proposal.

“Nancy Pelosi thinks that Walls are ‘immoral,’ why isn’t she requesting that we take down all of the existing Walls between the US and Mexico, even the new ones just built in San Diego at their very strong urging. Let millions of unchecked ‘strangers’ just flow into the US,” Trump tweeted about the House speaker.

The California Democrat has remained steadfast in her opposition to giving the president the $5.7 billion he has demanded, and Trump has been equally insistent that he won’t sign bills that would reopen the government until he gets his way.

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

Trump on Sunday branded Pelosi a “radical,” and said she was acting “irrationally.”

The president also tried to fend off criticism from the right, as conservative pundit Ann Coulter and others on the right 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 to protect the so-called Dreamers.

With hundreds of thousands of federal workers set to face another payless payday this week, the issue passed to the Senate, where Majority Leader Mitch McConnell has agreed to bring Trump’s proposal to the floor this week.

Democrats say there’s little chance the measure will reach the 60-vote threshold usually required to advance legislation in the Senate.

Republicans have a 53-47 majority, which means they need at least some Democrats to vote in favor.

What’s unclear is how McConnell will bring Trump’s plan forward — or when voting will begin.

Democrats continue to say that they will not negotiate with Trump until he ends the shutdown, the longest in American history, and the Democratic-controlled House planned to advance legislation this week that would reopen the government.
