Liar, possibly.
Criminal under Deleware State Law, probably not.
I didn't see anything in the Deleware statutes violated by the fact pattern given in the article, assuming both Bradys were residents of DE and both were legally allowed to own firearms.
(Standard disclaimer applies: I am not, nor do I wish to be, admitted to Deleware State Bar.)
There are prohibitions against "selling" a gun to another person by a non-dealer without first going to a dealer to get a criminal background check on the buyer, but no prohibition on giving, lending, or leasing.
