Sen. Marco Rubio, R-Fla., is planning a “special announcement” on wireless spectrum Wednesday at an invitation-only event planned in Washington. Rubio will host a 3 p.m. fireside chat and question-and-answer session at 1776, a tech hub for Washington startups. Rubio plans “to discuss the importance of spectrum reform in encouraging innovation in the 21st century,” said a Tuesday media advisory. In March, Rubio had said he would introduce legislation calling for the reallocation of 200 MHz of federally held spectrum for commercial use. He has yet to introduce the legislation. A spokesman for Rubio did not comment on whether he would introduce the bill Wednesday.
