Story highlights The Republican is traveling in Europe on Senate business

Some of the town halls held by other lawmakers have turned raucous

Washington (CNN) A progressive group in Florida is planning an "empty chair" town hall targeting Sen. Marco Rubio while the Republican is traveling in Europe on Senate business, rather than in the state holding public meetings with constituents.

Some of the town halls held by other lawmakers have turned raucous, with liberal activists and others pressing GOP lawmakers on dismantling Obamacare, implementing tough new immigration rules and where they stand on other controversial policies emerging from President Donald Trump's administration.

A frustrated Rubio staffer dismissed the empty-chair event as "not a true or constructive dialogue."

"The protesters -- some of whom failed to show up for meetings they scheduled with our staff -- continue to fundraise off of it even though we informed them days ago Senator Rubio will not be there," Rubio spokesman Matt Wolking said. "We have been fully accessible and responsive to constituents, and our staff has already met with dozens of these liberal activists at our offices across Florida. As their manual reveals, their goal is to stage a hostile atmosphere, record themselves booing no matter what is said, and refuse to give up the microphone. That is not a true or constructive dialogue."

One Internet posting by the liberal group publicizing the event, Indivisible Tampa, said: "Citizens of Tampa are organizing a town hall event during the Congressional recess for Sen. Marco Rubio to address urgent concerns regarding health care, national security, and the President's links to Russia. We have invited Sen. Rubio to attend but cannot be certain he will attend"
