President Trump erased a few of his tweets that promoted Sen. Luther Strange on Tuesday after his preferred candidate lost to Roy Moore in a GOP runoff contest to compete in the general election for Alabama's U.S. Senate seat.

Politwoops, a project of ProPublica which tracks deleted tweets from public officials, archived three tweets that were deleted less than 24 hours after they were sent, all promoting Stange's candidacy.

These three tweets Trump deleted, however, are not the only ones he's sent out in support of Strange, and his older tweets from last week and over the weekend remain untouched as of press time.

Trump has deleted tweets in the past, including one in May when he abruptly ended an incomplete thought with "covfefe," which earned him widespread mocking on the Internet. In June, Trump was sued by two groups, Citizens for Responsibility and Ethics in Washington and the National Security Archive, in part over his deleted tweets, accusing him of breaking federal law by destroying federal records.

Trump offered congratulations to Moore after Strange conceded the race Tuesday evening.

If he follows through on a pledge he made at a Strange rally in Alabama on Friday, Trump will campaign for Moore in the general election against Democrat Doug Jones.
