Obviously not. The idea that information has value is an age-old one that is firmly established in the law. It is, for example, the basis for claiming damages in any number of contractual arrangements. The slippery slope here is the one you're headed down when, for the sake of defending the Trump administration, you want to assert the existence of an invisible clause in campaign finance law that says that a thing of value cannot include valuable information. If we go down that slope then, as I've explained, you may as well not have such laws, since anyone can then spend any amount on any campaign, so long as the services provided are confined to information services.
That depends entirely on the context, obviously. If it's an ordinary exchange of information where the campaign is just asking questions to gather information as ordinarily happens, then it would not be a violation, since it then isn't a donation to the campaign. But picture if, instead, Mexican agents were to contact a Democratic campaign and offer to meet with the Clinton campaign in order to provide valuable information from cyber-espionage, damaging to Donald Trump, expressly as part of the Mexican government's efforts to get Clinton elected. What if the Clinton people were so lacking in patriotism that rather than report that to the FBI, they agreed to the meeting, so they could solicit that valuable donation. Would that be a campaign finance violation? Of course it would.
Yes, and information has value, too. Companies spend billions of dollars on R&D for example, where the only product is information. Often the investment dwarfs the cost of buying a whole fleet of planes. But you want to assign the value of $0 to that information.... not because it is remotely sane to do so, but because you think that's the path to excusing the Trump campaign's conduct.
EXACTLY! In the same way, being offered stolen goods is not a crime, but conspiring to receive stolen goods is. If someone offers to sell you something you know they have no legal right to sell you, and you go to the cops about it, you're simply doing your civic duty. If, instead, you agree to meet with them to arrange for the transfer of the goods, you're committing a felony. What Trump Jr. (and Kushner and Manafort) did was equivalent to arranging to meet with a fence to take possession of stolen goods.
As you know, you will say every single criminal act by Trump in his campaign is a "nothing burger," no matter what, because that's the exact point handed down by the conservative apparatchiks. Let me guess: Trump's conspiracy to pay off Stephanie Clifford and the other sex worker, to protect his campaign, without disclosure (in contravention of campaign finance law) was also a "nothing burger," right?
