“At minimum, we have to deal with the family situation,” McCaul, R-Texas, who is the chairman of the House Homeland Security Committee, said during an interview on “Fox News Sunday” with Chris Wallace.
McCaul added that he believes the updated immigration legislation will pass in the House next week.
It would also finance Trump's aspirational $25 billion wall with Mexico and curb government agencies from wrenching migrant children from detained parents.
Even if McCaul can garner enough Republican votes to pass the immigration legislation through the House, it is seen as unlikely to get past a filibuster in the Senate.
Former Homeland Security Secretary under President Obama, Jeh Johnson, said on "Fox News Sunday" that curbing the flow of women and children coming across the U.S. border illegally is something that will not happen overnight and the country needs to address the root cause of the problem.
