They'll tour the Carrizo Springs facility operated by the Department of Health and Human Services. The Biden administration reopened the shelter in February to accommodate more than 700 migrant children amid a surge of minors seeking asylum at the border in recent weeks.

Press will not be allowed to join the Democratic lawmakers inside the facility, per guidelines from the Biden administration, but the members of Congress will hold a news conference outside the shelter afterward at 1 pm. EST on Friday, her office said.

CRUZ, CORNYN TO LEAD SENATE DELEGATION TO BORDER, AS GOP RAMPS UP PRESSURE ON BIDEN OVER BORDER CRISIS

Meanwhile, a group of 18 GOP senators will be in Texas Friday to observe the conditions at the border.

Some of those attending with Texas GOP Sens. Ted Cruz and John Cornyn held a news conference Wednesday at the Capitol blaming Biden's rhetoric and executive orders for the migrant surge and criticizing his administration for denying press access to the border facilities. 

"If they're not going to allow the press into these facilities, that really is unfortunate," said Sen. Mike Lee, R-Utah. "We'll do what we can to be your eyes and ears and communicate the information we're able to acquire while we're there."

On Wednesday, a delegation of White House officials and members of Congress toured the Carrizo Springs facility in rural Texas and allowed one TV network crew inside with them to cover the visit.

The pool reporter inside found there were 766 minors at the facility, and at one point the numbers reached about 800.
