WASHINGTON — House Democrats are introducing a package of bills Monday that would re-open the federal government without approving funding for President Donald Trump’s border wall with Mexico, establishing an early confrontation that will test the new power dynamic in Washington.

The House is preparing to vote as soon as the new Congress convenes Thursday, as one of the first acts after Democrats take control, according to an aide who was not authorized to discuss the plan and spoke on condition of anonymity.

Democrats under Nancy Pelosi are all but certain to swiftly approve the two bills, making good on their pledge to try to quickly resolve the partial government shutdown that’s now in its second week. What’s unclear is whether the Republican-led Senate, under Majority Leader Mitch McConnell, R-Ky., will consider either measure — or if Trump would sign them into law.

The White House did not immediately respond to a request for comment. The package does not include the $5 billion Trump wants for the wall on the southern border. The president insisted in a series of tweets Monday he still wants to build the wall, a signature campaign promise.

McConnell spokesman Donald Stewart made it clear Senate Republicans will not take action without Trump’s backing. “It’s simple: The Senate is not going to send something to the president that he won’t sign,” he said.

Republican senators are refusing to vote on any bills until all sides, including Trump, are in agreement. Senators were frustrated that Trump had dismissed their earlier legislation to avert the shutdown.

House Democrats did not confer with Senate Republicans on the package, but the bills expected to have some bipartisan support because they reflect earlier spending measures already hashed out between the parties and chambers.

One bill will temporarily fund the Department of Homeland Security at current levels, with $1.3 billion for border security, through Feb. 8, while talks continue.

The other will be on a measure made up of six other bipartisan bills — some that have already passed the Senate — to fund the departments of Agriculture, Interior, Housing and Urban Development and others closed by the partial shutdown. They would provide money through the remainder of the fiscal year, to Sept. 30.

The House is planning two separate votes for Thursday. If approved, the bills would go to the Senate.

Senate Democrats support the measures, according to a senior aide who was unauthorized to discuss the plan and spoke on the condition of anonymity.

Without funding for Trump’s wall, the package is a “nonstarter,” said Rep. Mark Meadows, R-N.C., the chairman of the conservative House Freedom Caucus, in a tweet. He said it “will not be a legitimate answer to this impasse.”

But as the shutdown drags on, pressure is expected to build on all sides for a resolution, as public parks and museums close, and some 800,000 federal workers are going without pay.

Trump could accept or reject either bill, and it’s unclear how he would respond. The president continued to insist Monday he wants to build a wall along the U.S.-Mexico border, despite assertions otherwise of three confidants.
