Ron DeSantis, who's seeking the Republican nomination for governor, was radio silent on Twitter about the two-year anniversary of the Pulse nightclub shooting in Orlando — the only candidate from either party not to acknowledge the anniversary Tuesday.

As of Wednesday afternoon, the most recent tweet from the Republican congressman's @RonDeSantisFL campaign account wished President Trump a "great birthday." (Trump turns 72 Thursday.)

DeSantis' second-most recent post was about an  endorsement he got from a conservative media personality. The most recent tweet from his congressional @RepDeSantis account was a retweet about Trump's North Korea summit.

A DeSantis spokesman did not immediately respond to multiple questions about other ways the congressman may have acknowledged the anniversary. A review of DeSantis' Facebook and Twitter pages turned up no recent mention of the shooting.

DeSantis did post about the anniversary in 2017.

DeSantis' Republican opponent Adam Putnam and all four Democratic candidates with active Twitter accounts acknowledged the second anniversary shooting Tuesday. (A fifth Democrat, real estate tycoon Jeff Greene, does not have an active Twitter.)

Agriculture Commissioner Putnam tweeted Tuesday, "We will never forget" minutes before a statewide day of silence to honor the victims.

Some on the left criticized Putnam's statement, saying it didn't go far enough to honor the LGBTQ victims of the shooting.

Another prominent Republican who'll be featured on ballots in 2018, Gov. Rick Scott, drew praise for wearing a rainbow ribbon to honor the victims.

But he also drew his share of heat from some LGBTQ advocates, who criticized his record on LGBTQ issues. And Democratic Sen. Bill Nelson, Scott's opponent in the 2018 race for Florida's U.S. Senate seat, tweeted that the governor did not do enough to protect Florida from gun violence in the wake of the Pulse shooting.
