Sen. Ted Cruz (R-Tex.) said Sunday that a pathway to citizenship for undocumented immigrants would be unfair to those who have legally immigrated to the United States.

"I think a path to citizenship for those who are here illegally is profoundly unfair to the millions of legal immigrants who followed the rules,” Cruz said during an interview for ABC's "This Week."
Cruz added that he does not think a bill with such a path can pass the Republican-controlled House.

The Texas senator, a favorite among tea party voters, brushed aside questions about whether he is considering a run for president in 2016, and whether he would be ready for that role after just one term as a federal lawmaker.

"We are having a national debate about which direction the country should go…and what I am doing now is trying to participate in that national debate,” Cruz said during his interview from Iowa, a state frequented by politicians with White House ambitions. “I’m not focused on the politics.”

ABC News's Jonathan Karl asked Cruz about his eligibility for the White House, which has been questioned because the senator was born in Canada. Cruz noted that his mother was born in Wilmington, Del.

"She’s a U.S. citizen, so I’m a U.S. citizen,” Cruz said. “I’m not going to engage in a legal debate. The facts are clear.”
