On Day 84, Vice President Kamala Harris unveiled her philosophy on stemming migration: giving “hope” to the Northern Triangle that help is on the way. President Biden Announces Troop Withdrawal From Afghanistan. Joe Biden announced that full troop withdrawal from Afghanistan is set to begin on May 1, 2021, and be completed by September 11, 2021, as he attempted to push the news cycle away from his party’s incitement of riots, and his government’s failure to protect the U.S. border. “We delivered justice to bin Laden a decade ago, and we’ve stayed in Afghanistan for a decade since,” Biden said in remarks from the Treaty Room. “Since then, our reasons for remaining in Afghanistan are becoming increasingly unclear, even as the terrorist threat that we went to fight evolved.” Biden also alluded to “a significant downside risk to staying beyond May 1st without a clear timetable for departure,” referring to the original date for troop withdrawal negotiated by former president Donald Trump. Vice President Kamala Harris has announced her first official trip abroad to Mexico and Guatemala, but the jaunt will not include the U.S. southern border.
