Former Maryland Governor Martin O’Malley will sign a lease for a 7,200 square foot office space in Baltimore ahead of a possible bid for the Democratic nomination for the White House in 2016, Fox News has confirmed.

The Baltimore Sun first reported Thursday that O’Malley plans to close the Washington D.C. office of his PAC – “O’Say Can You See” -- and move into the Baltimore offices, along with 40 workers, by the middle of next week.

O’Malley spokesperson Lis Smith confirmed the report to Fox News.

O'Malley, who served two terms as Maryland governor between 2007 and 2015, will make an announcement on a potential 2016 bid on May 30 in Baltimore, the city he ran for eight years as mayor.

If he runs, he would be the third Democrat to declare his candidacy for the White House, after former Secretary of State Hillary Clinton and Vermont Sen. Bernie Sanders.

O’Malley’s PAC has boosted its staffing and made several new hires in the last few weeks.

In a closed-door meeting with top liberal activists and academics in New York on Monday, O’Malley pitched himself as the progressive alternative to Clinton, a source told Fox News. O’Malley cited his opposition to the Asia-Pacific free-trade deal, as well as other issues of importance to the progressive wing of the Democratic party as rallying points for his potential candidacy.
