Senator Marco Rubio is still trying to wrap his head around the Miami Dolphins firing of (ex-) head coach Brian Flores ... telling TMZ Sports he was "just as surprised as anybody."
"I don't know what happened inside that building you know," Rubio said. "I was just as surprised as anybody. I don’t think anybody was expecting that today."
The U.S. Senator from Florida -- who was born in Miami -- told us he didn't want to speculate on what went wrong in Miami ... but he believes something transpired that ultimately led to the demise of Flores.
