Democrats want to show voters that they're with workers, drawing on labor union support for the opening night of the convention.

"We are all in for Kamala Harris because Kamala Harris has always been all in for us," said April Verrett, president of the Service Employees International Union, or SEIU.
Verrett was among the group of union leaders who took to the stage to counter the courting of blue-collar workers by former President Donald Trump, who invited the head of the Teamsters to speak at the Republican National Convention. Teamsters President Sean O'Brien was not among the union leaders speaking at the Democratic convention on Monday.
The crowd waved "UNION YES!" signs as the leaders spoke. Most union households have backed Democrats, helping the party win in key states such as Michigan, Pennsylvania and Wisconsin in 2020.
Liz Shuler, head of the AFL-CIO, said that Trump's plans were "a CEO's dream, but a worker's nightmare."
