ATLANTA -- Leading congressional Democrats are reacting furiously to lightly-substantiated claims that immigrants held at a detention centre in Georgia are undergoing questionable hysterectomies.

In a complaint filed Monday, a nurse alleges that the Irwin County Detention Center performed questionable hysterectomies, refused to test detainees for COVID-19 and shredded medical records. Democrats seized on the most explosive allegations in her complaint -- that a gynecologist called the "uterus collector" was performing "mass hysterectomies."

They declared they would investigate the matter.

A follow-up news conference Tuesday in Atlanta provided little information to substantiate the claims.
