Marco Rubio rants about unnamed sources in Twitter tirade

Former Republican hopeful Marco Rubio offered a glimpse of his future on Monday — and it appears to involve a lot of working out.

The Florida senator unleashed a late-night Twitter tirade that included sarcastic tweets about “whether to chest or legs tomorrow at gym.”

The rant followed a story in the Washington Post that suggested he was lost at sea in terms of his political future.

“Rubio, according to conversations I’ve had with people close to him, is sort of betwixt and between when it comes to his next move,” according to Monday’s story by the Post’s Chris Cillizza.

In response, the 44-year-old Rubio issued a flurry of messages about how he was spending his time, his ambitions and reporters “desperate for content.”

Rubio suspended his campaign on March 15 after failing to win his home state of Florida to presumptive Republican nominee Donald Trump, who had mocked his younger adversary for his Senate absences and called him “Little Marco.”

Rubio’s decision to go negative against Trump — and at one point making apointed reference to the size of the real estate magnate’s hands — dented his popularity.

His tweets have taken on a different tone than during his campaign, and have picked up in pace since he dropped out of the race.
