One of President Barack Obama's economic advisors will join Hillary Clinton's campaign in another sign of close coordination between the White House and the presumptive Democratic nominee.

Jacob Leibenluft, deputy director of the National Economic Council, will become a senior policy advisor as Clinton prepares to fill out her economic agenda for the general election.

On Tuesday, she plans to deliver a speech in Columbus, Ohio, that will contrast her proposals to lift middle-class incomes with Donald Trump's business record, which she will argue is characterized by self-interest at the expense of others.

Leibenluft has served on Obama's economic team from the beginning of the president's first term. Among his areas of focus have been policies on job training, apprenticeships and the minimum wage.

Jared Bernstein, a former administration colleague, described Leibenluft as a "very strong, fact-based analyst." He joins a Clinton team that includes other ex-White House aides such as campaign chairman John Podesta and communications director Jennifer Palmieri.
