Muslim American mayor says border agents wrongfully detained him

What they're saying: Anthony Bucci, a public affairs officer with CBP, told CNN the agency could not speak about specific events because of the Privacy Act. However, he said CBP's "authority to engage in border searches is articulated in numerous statutes and has been repeatedly affirmed by the Supreme Court of the United States."

• Khairullah said an agent told him that he was randomly selected for questioning, but he said he doesn't believe it and has not ruled out legal action against CBP.
• Ahmed Mohamed, director for New York's Council on American-Islamic Relations, a Muslim American civil rights group, said he is representing Khairullah in what he described is "a clear case of profiling."

The big picture: If Khairullah sues the agency, he would be joining other advocates who are currently challenging CBP's authority in federal court.

• The American Civil Liberties Union and the Electronic Frontier Foundation in 2017 filed a lawsuit challenging the Department of Homeland Security, the CBP and Immigrations and Customs Enforcement's authority to seize and search people's electronic devices at the border without reasonable suspicion or a warrant.
