Trump Campaign Statement on Obama Endorsement of Biden
"Barack Obama spent much of the last five years urging Joe Biden not to run for president out of fear that he would embarrass himself. Now that Biden is the only candidate left in the Democrat field, Obama has no other choice but to support him. Even Bernie Sanders beat him to it. Obama was right in the first place: Biden is a bad candidate who will embarrass himself and his party. President Trump will destroy him."
- Brad Parscale, Trump 2020 campaign manager
