O’Malley will joined in his attack on the former Massachusetts governor by South Carolina state Rep. Terry Alexander, a Democrat from Florence County.

Romney and other GOP presidential hopefuls are spending much of the week in South Carolina in advance of Saturday’s primary there. A Romney win would put him on strong footing to secure the party’s nomination.

O’Malley is expected to be a leading surrogate for President Obama as the general election nears. The governor has defended the president’s record in recent national television appearances and other settings.

On Monday night, O’Malley plans to stay in Myrtle Beach to offer reaction to the Republican presidential debate being sponsored by Fox News and the South Carolina Republican Party.

An aide said O’Malley will be back in Maryland by Tuesday morning to brief lawmakers and others on his budget proposal, which is due to the General Assembly on Wednesday, a week into the 90-day legislative session.
