A Border Patrol agent was assaulted and even bitten by a migrant who was part of a group attempting to illegally cross into the United States at the southern border Thursday afternoon, federal officials said.

Senior U.S. officials and migrant advocates say Mexico’s internal migrant bussing is a major factor in the stunning fall in apprehensions at the U.S. border, down 77 percent since December. But it’s unclear whether the results are sustainable.

A House Homeland Security Committee report is ripping in to the handling of the crisis at the southern border by the Biden-Harris administration, accusing it of fueling the crisis.

The former Border Patrol official responsible for securing nearly 1,000 miles of America’s frontier has charged that the Biden-Harris administration intentionally covered up the ongoing migrant crisis.

Former senior-ranking U.S. Border Patrol official Aaron Heitke alleged in testimony given before House lawmakers that the Biden-Harris administration purposely covered up the crisis at the southern border as millions of migrants illegally entered the United States.

The former chief patrol agent said arrests of 'significant interest aliens' have increased since President Joe Biden took office.
