"I've set the table".
A senior USA administration official said Trump will "present a path forward" on the wall impasse during the televised speech but declined to offer details.
"I think there's a good chance that we'll have to do that", he added, referring to declaring a national emergency.
In the interview with CBS Face the Nation, the president attempted to portray the shutdown that ended last month without funding for his wall as a victory over Nancy Pelosi, the Democratic House speaker.

All eyes are on Trump's Tuesday State of the Union address, when he is expected to make some sort of border wall announcement.
"With Caravans marching through Mexico and toward our Country, Republicans must be prepared to do whatever is necessary for STRONG Border Security".
He assailed House Speaker Nancy Pelosi, leader of the Democratic-controlled House of Representatives, for continuing to oppose US taxpayer-funding of the wall.
Trump has repeatedly threatened to declare a national emergency on the border, which he says would allow him to transfer money from elsewhere in the government to build his promised border wall without congressional approval.

Trump said he wants to keep the US military base in Iraq rather than pull troops out like in Syria and Afghanistan "because I want to be able to watch Iran".
