President Trump just went under the bridge where refugees and asylum seekers are being held

We know. Trump already admitted the emergency was fake news.

New government documents reveal that over 5,800 complaints of sexual abuse from unaccompanied minors were reported to the Department of Health and Human Services and the Department of Justice between the years of 2014 and 2018. The documents were released by Democratic representative Ted Deutch of Florida, during a hearing on the Trump administration’s “zero tolerance” immigration policies, which have led to a dramatic increase in the number of people — specifically children — detained by the U.S. government.

“I am deeply concerned with documents that have been turned over by HHS that record a high number of sexual assaults on unaccompanied children in the custody of the Office of Refugee and Resettlement,” said Deutch during the hearing. “Together, these documents detail an environment of systemic sexual assaults by staff on unaccompanied children.”

“These documents demonstrate over the past three years there have been 154 staff-on-unaccompanied-minor — let me repeat that, staff-on-unaccompanied-minor — allegations of sexual assault,” Deutch continued.

According to Axios, who first reported on the documents, that number may actually be slightly higher. According to their review of the HHS documents (which detailed all of the complaints to HHS and DOJ), of the 1,303 complaints filed to the DOJ, 178 of the allegations named an adult staff member as the abuser.

Some of the allegations in the documents included reports that adult staff members formed relationships with detained minors, showed children pornographic videos, and forcibly touched minors’ genitals. Investigations into the allegations often ended in the termination of the staff member, according to the documents.

"Don't worry. It's not really an emergency."

Not only did Trump admit that, if there is no emergency, then all the people in detention need to be released. No emergency means no reason to detain people means release them so they can get on with their lives.
