According to his campaign website, the three-term congressman will travel to the early nominating states of New Hampshire, South Carolina and Iowa this week.

Moulton, 40, has said for months that he was considering a 2020 run.

He told ABC News early Monday that Democrats have ceded issues such as patriotism, security and service to Republicans “for too long.”

“This is actually where Donald Trump is weakest,” he said. “We’ve got to take him on on these issues.”

“Seth Moulton is a Massachusetts liberal who supports higher taxes and the socialist Green New Deal," Republican National Committee spokesman Michael Ahrens said in a statement. "His presidential bid is going nowhere, just like his unsuccessful business career and his repeated failed attempts to challenge the least popular politician in DC: Nancy Pelosi."
