Texas Lt. Governor Dan Patrick deleted a tweet with a Bible verse posted as news broke of a mass shooting in an Orlando gay nightclub.

At 7 AM Sunday, Patrick tweeted from his personal account: “Do not be deceived. God cannot be mocked. A man reaps what he sows.”

Fifty people died and 53 others were injured in what is being described as the worst mass shooting on American soil.

The Texas Democratic Party called on Patrick to apologize.

Patrick's adviser Allen Blakemore called the tweet an unfortunate coincidence.

“Lt. Governor Patrick and every Texan is stunned and saddened by the outrageous act of domestic terrorism that has occurred in Orlando,” Blakemore said in a statement. “Regarding this morning's scripture posting on social media, be assured that the post was not done in response to last night's tragedy. The post was designed and scheduled last Thursday.”

The tweet was deleted before noon. Patrick is a Republican opposed to LGBT rights.
