ANNAPOLIS, Md. (AP) - Gov. Martin O'Malley is urging supporters of raising the minimum wage in Maryland to sign a petition.

The Democratic governor in an email from his political action committee on Thursday says he believes the state must make the choice to raise the minimum wage, which is currently $7.25 an hour.

O'Malley says is expecting a long and difficult effort. A measure to raise the minimum wage from $7.25 an hour to $10 by 2015 stalled in a Senate committee in the last legislative session.
