Gov. Martin O'Malley declined to comment Thursday on Dwyer's involvement in the collision, but through a spokeswoman said he "is very concerned for those who were involved in the crash and wishes for a speedy recovery."
Michael E. Busch was not available for comment.
"Many questions still remain after Delegate Dwyer's statements, but we appreciate the candidness of his remarks and expect that more answers will be forthcoming in the near future," the Republican State Central Committee of Anne Arundel County said in a statement released Thursday night.
Like others, the committee praised those involved in the rescue and expressed concern for the people who were injured.
