Funding is set to expire on Dec. 7 for some federal agencies including the Department of Homeland Security and Internal Revenue Service, which would trigger a partial shutdown unless lawmakers can navigate an impasse with Trump over spending on border security. Trump now says he may extend that deadline by two weeks.

If lawmakers “come, which they have, to talk about an extension because of President Bush’s passing, I would absolutely consider it and probably give it,” Trump told reporters aboard Air Force One en route to Washington from the Group of 20 Summit in Buenos Aires.

Trump has so far demanded funding for increased security at the U.S.-Mexico border, which would include a wall that he vowed to construct during his presidential campaign. He has said he is willing to endure a partial government shutdown if Congress fails to provide for border security in a spending bill.
