Florida was admitted to the Union on March 3, 1845, and elects its U.S. senators to class 1 and class 3. Florida's U.S. Senate seats were declared vacant in March 1861, due to its secession from the Union. They were filled again in July 1868. The state is currently represented by Republicans Marco Rubio (serving since 2011) and Rick Scott (serving since 2019). Duncan U. Fletcher was Florida's longest-serving senator (1909–1936). Florida is one of fifteen states alongside Arizona, Colorado, Georgia, Hawaii, Idaho, Indiana, Louisiana, Maine, Massachusetts, Minnesota, Missouri, Nevada, South Dakota and Utah to have a younger senior senator and an older junior senator.
