MADISON, Wis. (AP) — A Syrian refugee living in Dane County has filed a federal lawsuit alleging President Donald Trump's executive order halting immigration from seven countries is unconstitutional.

The man filed anonymously to protect his wife and 3-year-old daughter, who are still in Aleppo, from being targeted by military regimes.

He had applied for them to join him in the United States, but his lawsuit says processing was halted Jan. 27 when Trump temporarily stopped immigration from seven predominantly Muslim countries.

The lawsuit says the man was granted asylum status in May 2016 after he fled Syria to escape torture by army regimes. The lawsuit says as his case was pending, his 3-year-old son fell three floors to his death in 2015 while attempting to escape rocket fire that hit their home.
