Tucker is making a straw man fallacy.
This is the law:
52 U.S. Code § 30121
It shall be unlawful for
(1) a foreign national, directly or indirectly, to make—
(A) a contribution or donation of money or other thing of value, or to make an express or implied promise to make a contribution or donation, in connection with a Federal, State, or local election;
(B) a contribution or donation to a committee of a political party; or
. . . .
(2) a person to solicit, accept, or receive a contribution or donation described in subparagraph (A) or (B) of paragraph (1) from a foreign national.
The issue is whether Jr. (or someone else on Trump's team) solicited a "thing of value" (information) from the Russians (a foreign national) in connection with the election.
