State Rep. Seth Moulton will end his bid for the Democratic Party’s presidential nomination in a speech Friday afternoon, his campaign said. He is also expected to announce he will seek re-election to Congress.

The Salem Democrat, who was the second member of the Massachusetts congressional delegation to wade into to the crowded fray of Democratic candidates for 2020, will make the announcement in a speech at the Democratic National Committee’s Summer meeting.

As he ends his presidential campaign, Moulton is expected to talk about the importance of service and how his campaign helped to chip away at the stigma of mental health issues, especially among fellow veterans. He also will pledge that he “will be campaigning my ass off for whoever wins our nomination in 2020.”

“As a party, we need to spend these next months doing everything we can to determine who our strongest nominee will be. And as we do so, we can’t be distracted by the latest outrage on Twitter or the reality show politics of the day,” Moulton will say, according to a copy of his prepared remarks.

“We need to stay grounded in what it’s going to take to win over voters – all kinds of Democrats, Independents like the Obama-Trump voters, and even disaffected Republicans – and bring the country together around beating Donald Trump. Because you can be a Democrat, or a Republican, or an Independent. But if you’re an American, you know that we’re better than this.”
