A US Senator wants to question the Smithsonian on the gift of four Stradivarius violins it received from Herbert Axelrod, a New Jersey businessman who is on the lam in Cuba after being indicted for tax evasion. “It is troubling that the Smithsonian may be turning a blind eye to tax mischief. Government agencies should be working in concert, not against each other. . . . Donors shouldn’t be able to get away with playing the taxpayers like a fiddle.”
