Marco Rubio is putting critics of his pivot toward Donald Trump on notice one tweet at a time.

After months on the trail as a presidential hopeful vying against Donald Trump and a host of others whose bids similarly fizzled, recent tweets from the Florida senator have signaled that he will be tweeting his mind and returning his feed to its pre-campaign days, when tweets about politics and policy mixed with Super Bowl observations, for example.


"Hope media will start to report truth, many of the violent protestors @realDonaldTrump events are 'professional protestors'.Not grassroots," Rubio wrote Thursday morning, following up minutes later, "Whole industry of professional disrupters who go 2 events 2 disrupt them knowing cameras will gravitate to them.These protests not organic."

The tweets came hours before Rubio told CNN's Jake Tapper that not only would he attend the Republican National Convention, he would also be willing to speak for Trump and expected his delegates to be released for the Manhattan businessman who officially locked up the nomination on Thursday. Trump tweeted later Thursday night that Rubio should run for his Senate seat, a prospect the senator called "unlikely" on Thursday while still leaving the door open a crack, however small.

On Friday morning, Rubio responded directly to Washington Examiner's Philip Klein on Twitter after he tweeted his column headlined "Donald Trump has exposed Marco Rubio."

"Funny piece by @philipaklein. Easy to be a 'keyboard cowboy'.I actually ran & spent year away from home trying to prevent choice before us," Rubio tweeted.

And then he left little doubt in suggesting how he would cast his ballot come Nov. 8.

"In Florida only 2 legitimate candidates on ballot in Nov. I wont vote for Clinton & I after years of asking people to vote I wont abstain," he wrote. "If you can live with a Clinton presidency for 4 years thats your right. I cant and will do what I can to prevent it."

Rubio went off on an even lengthier tweetstorm on May 16 after The Washington Post's Chris Cillizza wrote that people "close to him" said he is "betwixt and between" when it comes to his future plans.

Funny to read about unnamed "people close" to me who claim to know my thinking on future plans.They just make it up. https://t.co/jiEYMugVHz — Marco Rubio (@marcorubio) May 17, 2016





Unnamed sources "close to" often just people who want to sound like they are in the know. And reporters desperate for content just accept it — Marco Rubio (@marcorubio) May 17, 2016





Word of advice, people often claim to know more than they really do because they enjoy status of being perceived as "in the know". — Marco Rubio (@marcorubio) May 17, 2016





I have only said like 10000 times I will be a private citizen in January. — Marco Rubio (@marcorubio) May 17, 2016





A source "close to Rubio" says he was tired after long day & has decided to sleep for a few hours before tomorrow's ZIKA debate in Senate. — Marco Rubio (@marcorubio) May 17, 2016





A "longtime friend" says Rubio is "betwixt and between when it comes to whether to chest or legs tomorrow at gym." — Marco Rubio (@marcorubio) May 17, 2016

He concluded: "Ok that's enough for one night. Twitter isn't something you should just rush back into. You have to slowly increase the dosage......."
