That Bill countain stuff that would effectively sanction/force European companies to stop working with russia(main energy supplier to Europe), Europe made it pretty clear that if those sanctions are applied to their companies Europe would counter sanction the U.S because they see it as interference into EU Energy Security. thats why he's doing nothing the bill says sanction european companies and Europe is saying NO.

(well it's also possible he's slacking off for other less rational reasons but actualy got it right by mistake on that one) .
