President Joe Biden said "there's nothing beyond our capacity if we work together" while addressing a gathering outside the National Museum of Slavery in Luanda, Angola, on Tuesday.

Biden is using his third and final day in Angola to showcase the Lobito Corridor railway, where the US and key allies are investing heavily to refurbish 800 miles of train lines in Zambia, Congo, and Angola.

Speaking of “our nation’s original sin,” President Joe Biden on Tuesday toured a slavery museum in Angola and inspected shackles and a whip but also addressed Africa’s future.
