The Republican governor said in February that he couldn't support the billionaire candidate after his friend, New Jersey Gov. Chris Christie, dropped out.
Asked by a reporter about Trump's comments in a 2005 video, in which he described grabbing women by the genitals and kissing them without their consent, Hogan called them "disgraceful and outrageous."
He noted that many Republican who are now saying they won't vote for the party's candidate.
"I believe I was one of the first people in the country to come out and say I wouldn't support Trump back in February. A lot of other people are joining that bandwagon," Hogan said.
Hogan added that he believes it's too late for Trump to drop out of the race. Early voting starts in Maryland on Oct. 27 and election day is Nov. 8.
At this point, people are going to vote "their conscious and vote for who they think is the best one for the job," he said.
His comments came during an endorsement of Mark Plaster, the Republican running for Congress in the 3rd District. Plaster has said he will vote for Trump but didn't comment on the governor's remarks or the video reported last week.
A spokesman for his campaign said after the event that Plaster had no comment on the tape.
