Maryland Democratic gubernatorial nominee Ben Jealous has promised that, if elected, he will honor any deal that Gov. Larry Hogan (R) makes to get Amazon.com to build its second headquarters in the state.

The comments, made in Montgomery County on Monday and first reported by Bethesda Magazine, are the first indication that Jealous supports efforts to lure the online behemoth to Maryland.

Jealous previously has criticized the state’s negotiations with Amazon, arguing that Maryland should invest in retaining and growing companies rather than offering multibillion-dollar incentives to Amazon. (The company’s chief executive, Jeffrey P. Bezos, owns The Washington Post.)

The Democratic nominee’s position on Amazon was one of several reasons that Montgomery County Executive Isiah Leggett (D) has held off on endorsing Jealous. Leggett said some of Jealous’s stances would penalize Montgomery County residents.

Kevin Harris, a senior adviser to the Jealous campaign, wrote in an email that Jealous “continues to have concerns about the lack of transparency and public notice for the deal.”

“But business leaders need to trust that when they negotiate deals, the state will honor those agreements,” Harris wrote.

A decision on the headquarters, also known as HQ2, is expected to be made this year.

Jealous is in an uphill battle against the governor, trailing Hogan in fundraising and polls.

Two recent ad buys highlight the advantage Hogan has.

The Republican Governors Association released an ad Tuesday defining Jealous as “too extreme.” The ad buy was $1 million. Meanwhile, the Jealous campaign released three ads Tuesday featuring a teacher, a small-business owner and a nurse who each tout the candidate’s plans to fully fund education, grow the economy and implement a Medicare-for-all program. That ad buy was $150,000.
