A Mexican immigrant who was brought illegally into the U.S. as a child has been detained, after being authorized to remain in the country as part of Obama's "Dreamer" program. Daniel Ramirez Medina, 23, was brought to the U.S. when he was seven years old, and was given a work permit during the Obama administration. Ramirez has a job, a son, and no criminal record, Northwest Immigrants Rights Project Legal Director Matt Adams told Associated Press. Officers arrived at his suburban Seattle home to also arrest his father, although court papers did not indicate why his father was taken into custody. "We are hoping this detention was a mistake," Ethan Dettmer, one of Ramirez's lawyer, told AP.
