Former President Joe Biden will be attending a Juneteenth celebration at a historic African Methodist Episcopal church in Galveston, Texas.

The event commemorating Juneteenth will be held at the Reedy Chapel African Methodist Episcopal Church in Galveston, Texas.

The U.S. government plans to open what amounts to a fly factory by the end of the year to breed millions of the insects in Texas near the border with Mexico as part of an effort to keep a flesh-eating parasite from infesting American cattle.

The facility will breed millions of sterile New World screwworm flies at Moore Air Base, Agriculture Secretary Brooke Rollins said Wednesday.

Screwworm is a parasitic fly that targets warm-blooded animals and has the potential to disrupt Texas’ $15 billion cattle industry.
