I know there are abuses, but simply agreeing with a lobbyists is nothing wrong. The MEP, it seems to me, has to think about businesses in Europe as well as individuals so there has to be a balance in the regulations. There could and should be lobbyists on both sides of an issue since all a lobbyists does is represent a group and bring their opinion to the decision makers. So here we have a business lobbyist convincing a conservative (pro business) MEP that the lobbyist's position has merit. Not a tough sell. Since US companies have a stake in the decision then their sharing their opinions is natural. If the MEP agrees with the lobbyists position then using their wording is no surprise.
So until someone starts talking about secret payments of some kind, all I see is someone being convinced.
