Sen. Lindsey Graham said Monday he would support legislation protecting beneficiaries of the Deferred Action for Childhood Arrivals program if President Trump gives lawmakers a window for finding a legislative option before canceling the program, which he's expected to announce Tuesday.

"If President Trump chooses to cancel the DACA program and give Congress six months to find a legislative solution, I will be supportive of such a position," Graham said in a statement. "I have always believed DACA was a presidential overreach. However, I equally understand the plight of the Dream Act kids who — for all practical purposes — know no other country than America."

Graham, R-S.C., with Sen. Dick Durbin, D-Ill., has already introduced legislation to legalize DACA's some 800,000 recipients.

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 will delay the termination of DACA for six months, according to multiple reports, to give Congress time to devise a legislative solution.

Graham collaborated in 2013 on a failed effort known as the Gang of Eight that would have provided a path to citizenship for immigrants living in the country illegally.

His support to fix DACA legislatively is also supported by one of the most conservative senators, Sen. James Lankford, R-Okla.

"It is right for there to be consequences for those who intentionally entered this country illegally," Lankford said Monday in a statement. "However, we as Americans do not hold children legally accountable for the actions of their parents."
