DHS Secretary grilled over \'cages\'

ROUGH CUT (NO REPORTER NARRATION) House Homeland Security Committee Chairman Bennie Thompson and Congresswoman Bonnie Watson Coleman questioned DHS Secretary Kirstjen Nielsen over whether or not migrant children were being kept in "cages." Homeland Security Secretary Kirstjen Nielsen visited the U.S. Capitol as the White House sought to discourage more Republican defections on the measure rebuking the president.

Republican senators had a "spirited discussion" on the matter, Senate Majority Leader Mitch McConnell said.

Trump declared an emergency at the border Feb.

15, saying this allows him to use money that Congress has appropriated for other purposes in order to build a border wall.

Trump says the wall is needed to stop illegal immigration and drug trafficking.

The Democratic-majority House of Representatives already has approved a measure to overturn Trump's border wall emergency, and the Republican-run Senate is expected to follow suit by the end of next week now that four Senate Republicans say they will join Democrats in passing it.
