Maryland Lt. Gov. Anthony G. Brown (D) announced Tuesday morning that a labor organization representing roofers, plumbers, bricklayers and other building trades workers in the region had endorsed his gubernatorial bid.

There was only one problem: It hadn’t happened yet.

Brown campaign manager Justin Schall said Tuesday afternoon that his camp “accidentally jumped the gun” on sending out a news release touting the support of the Community Hub for Opportunities in Construction Employment. The organization includes 28 unions that are part of the Washington D.C. Building and Construction Trades Council and the Baltimore Building and Construction Trades Council.

“There was some confusion on our part, and we have been informed that they will be making a decision in the near future,” Schall said.

Mark Coles, the labor organization’s executive director, said Tuesday afternoon that he was not ready to make an announcement.

“When we’re ready to make our position known on where we are, we’ll make it known, and we haven’t done that yet,” Coles said.

Brown, who has won the majority of labor endorsements in the Democratic race for governor, faces Attorney General Douglas F. Gansler (D) and Del. Heather R. Mizeur (D-Montgomery) on the June primary ballot.

Separately on Tuesday, Mizeur announced an endorsement by the Association of Flight Attendants, an international union.

“Heather understands the unique issues facing AFA members in Maryland, as well as the broad issues facing American workers,” Veda Shook, the organization’s president, said in a statement.
