You can read the proposed rule and the full notice and factsheet here: https://www.ftc.gov/legal-library/browse/federal-register-no...
Of note, an FTC commissioner (Trump appointee, so a minority voice in the executive atm) released a dissenting statement outlining the strategy that will be used to defeat the proposed rule: https://www.ftc.gov/system/files/ftc_gov/pdf/p201000noncompe... (warning: pdf). In her dissent, she speaks eloquently about how darn important noncompetes are to Business and Competition, and "encourage[s] all interested parties to respond fully to all parts of the NPRM’s solicitation of public comments."
Which, well... I'll also encourage all interested parties to respond fully to all parts of the NPRM’s solicitation of public comments! You can do so at regulations.gov
