Republican senators plan to prohibit services from offering end-to-end encryption, by a set of practices to be decided later by various agencies that want to snoop on everyone.

This will restrict the nonfree communications applications that are supplied by specific services. If you are wise, you will not trust them; you will use free programs, independent of whatever communications servers you use, to do the encryption. However, lots of other people will use those nonfree applications, and that will allow the US government to snoop on almost everyone in the US.
