House Speaker Nancy Pelosi hinted that she’s open to some new fencing but not a wall to boost border security, as President Donald Trump said he’s "not waiting" for a bipartisan committee to come up with a plan to avoid another government shutdown.

House Democrats on Thursday provided a detailed offer that would provide no funds for border barriers, though it shows the party is willing to provide billions in new funds for technology and personnel. The conference committee held its first meeting Wednesday in an effort to negotiate a deal, and staff talks are continuing.

Trump has threatened a new government shutdown after Feb. 15 if a spending bill doesn’t fund a wall or physical barriers.

"I’m not waiting for this committee," the president told reporters in the Oval Office. "Without a wall it doesn’t work." Earlier in the day, he tweeted that Republicans on the committee "are wasting their time."

"There’s not going to be any wall money in the legislation," Pelosi told reporters Thursday, while adding that additional technology and border infrastructure are "part of the negotiation."

There already are vehicle barricades known as Normandy fencing along the border, and "if the president wants to call that a wall, he can call it a wall," said Pelosi of California. "Is there a place where enhanced Normandy fencing would work?" she said, adding that members of the bipartisan conference committee should “have that discussion."

Pelosi said committee members will consider a “cost-benefit analysis” on the most effective and efficient way to secure the border. Top Democratic negotiator Nita Lowey of New York, chairwoman of the Appropriations Committee, declined to comment Wednesday when pressed on whether she would accept any new fencing money.

Texas House Democrat Henry Cuellar said some new fencing could be possible if local authorities can control where it goes.

The Democrats’ offer includes US$98 million for 1,000 new customs officers, US$675 million for more imaging technology at land ports of entry, US$400 million for other border technology procurement and US$502 million for humanitarian aid for migrants.

The next meeting of the main negotiators is expected early next week. Pelosi said the committee needs to complete an agreement by Feb. 8 to get it through Congress by Feb. 15.
