On 21 July 2024 President Biden withdrew and endorsed Kamala Harris; she launched a presidential campaign and became the Democratic nominee on a compressed timetable.
Context
Delegates consolidated. Neighbouring 5 November loss is later. She did not write the party charter.
5 November 2024 is the child result. 20 January 2021 oath is the parent office.
The Vice President of the United States presides over the Senate, casts tie-breaking votes, and carries delegated White House portfolios. She does not write House bills, CBP operational orders, or Federal Reserve rate decisions. A vice president is not co-author of every presidential statute.
Why it matters
The path is democratic resilience: a completed mid-cycle nomination is a dated party-succession instrument.

What the sources establish
Democratic National Committee carries the official instrument or communique. Reuters records the same dated act independently.
Established: 21 July 2024 Biden withdrawal and Harris launch, independently reported; she became the nominee.
She launched. Delegates voted. The convention sat.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Harris becomes the Democratic presidential nominee after Biden withdraws, not a later speech about Harris becomes the Democratic presidential nominee after Biden withdraws.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Biden withdrew and endorsed. She launched. Delegates voted. The convention sat. That limit is the alternative to treating office-holding as authorship of every later series.
