House Democratic Leader Nancy Pelosi said Monday President Trump will be demonstrating "political cowardice" if he ends the Deferred Action for Childhood Arrivals program.

"President Trump's decision to end DACA should break the hearts and offend the morals of all who believe in justice and human dignity," Pelosi, D-Calif., said in a statement. "This cruel act of political cowardice deals a stunning blow to the bright young DREAMers and to everyone who cherishes the American Dream."

Trump on Tuesday is expected to declare he will end DACA, a program former President Barack Obama created unilaterally that protects certain immigrants who were brought illegally to the U.S. as children and gives them work permits.

The president is expected to delay the termination of DACA for six months, according to multiple reports, to give Congress time to devise a legislative solution to protect the 800,000 or so illegal immigrants who benefit from the program.

Pelosi called on Republicans to support such legislation.

"House Republicans must join Democrats to pass legislation to safeguard our young DREAMers from the senseless cruelty of deportation and shield families from separation and heartbreak," she said.
