The Facts

• Barack Obama endorsed current Vice Pres. Kamala Harris for the Democratic presidential nominee on Friday, with the former US president and his wife, Michelle Obama, telling her they would "do everything" to help her win.

• The Obamas praised Harris for what they described as her career achievements, including her time in California as a prosecutor, attorney general, and US senator, as well as her time as Pres. Joe Biden's vice president.

• Obama waited longer than other Democrats to endorse Harris, with reports indicating the delay was to allow time for Biden's public address on Wednesday and for more campaign donations to pour in, which totaled over $100M from Sunday to Monday.
