Former Maryland Gov. Martin O'Malley is scheduled to speak at the Democratic National Convention.
O'Malley, who ended his bid for the party's presidential nomination in February, is scheduled to speak Wednesday evening.
O'Malley dropped out of the race midway through vote-counting in the Iowa caucuses, after his campaign failed to gain traction against Hillary Clinton and Bernie Sanders.
The former governor endorsed Clinton last month.
In an announcement of his scheduled convention speech, O'Malley said he will make clear that Clinton is not only one of the most experienced candidates in the party's history, but also one of the toughest.
He says Clinton will fight for the marginalized and honorably represent the country in the world.
