Pushback is happening over vaccine requirements and mask mandates.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 615,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 58.4% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.
The CDC last week, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission -- vaccinated or not -- wear a face covering in public, indoor settings.
Florida has 12,408 COVID-19 patients in hospitals -- the highest number to date of the entire pandemic.
Florida hospitals report that more than 95% of COVID-19 patients are not fully vaccinated, according to state data.

Four COVID-19 patients at Regional Medical Center in Anniston, Alabama -- all unvaccinated -- died within 24 hours, marking the hospital’s deadliest day of the pandemic, The Anniston Star reported.
As delta surges, patients are now getting sicker faster, a doctor at the hospital told the newspaper.
Only 28% of residents in Calhoun County are fully vaccinated, according to The Anniston Star.
Former President Barack Obama has decided to "significantly scale back" his 60th birthday party on Martha’s Vineyard due to the spread of the delta variant, according to a spokesperson. Hundreds of guests were expected to attend.
"This outdoor event was planned months ago in accordance with all public health guidelines and with covid safeguards in place. Due to the new spread of the delta variant over the past week, the President and Mrs. Obama have decided to significantly scale back the event to include only family and close friends," spokesperson Hannah Hankins said in a statement.
Obama’s office did not give a new estimate of how many guests will attend.

President Joe Biden is calling out Florida Gov. Ron DeSantis and Texas Gov. Greg Abbott for rejecting mask mandates in their states.
"I believe the results of their decisions are not good for their constituents," Biden said of the governors at a Tuesday news conference.
Biden said Florida and Texas are accounting for one-third of the new COVID-19 cases in the country.
"We need leadership from everyone. If some governors aren't willing to do the right thing to beat this pandemic, then they should allow businesses and universities who want to do the right thing to be able to do it," Biden said. "I say to these governors, 'Please help. But if you aren't going to help, at least get out of the way.'"
