The Maryland gubernatorial campaigns were pressed Thursday on why they are not producing televisions ads with closed captioning during a forum that focused on issues of interest to people with disabilities.

Lt. Gov. Anthony G. Brown, the Democratic nominee, told the gathering in Baltimore that “cost is a factor” in providing the service that helps people who are deaf.

“The resources available to my campaign aren’t nearly the resources available in state government,” Brown said during the forum, which was hosted by the National Federation for the Blind. “I can assure you that my failure, if you will, to communicate with certain communities will not be indicative of how wide and far and deep that we communicate” in government.

Boyd Rutherford, who stood in at the forum for his running mate, Republican Larry Hogan, said the moderator had posed “a very good question.”

“I’m going to take it back to the campaign,” Rutherford said. “I don’t know why we haven’t done that. I’m not directly involved in the ad process, but that is something I will take back to the campaign and say from this point forward, we should be able to do that. … The cost should not be an issue here.”

Libertarian Shawn Quinn, who also appeared Thursday, said he had not been able to afford television ads but would provide closed captioning if he could.

The three candidates appeared separately at the forum, which focused on a range of issues, including employment, transportation and housing.
