Sabin came here from Bialystock Russian Empire and changed his name. Probably to avoid arrest. He was a traitor to his adoptive country and traveled “to Cuba in 1967 to discuss with Cuban officials the possibility of establishing a collaborative relationship between the United States and Cuba through their respective national academies of sciences, in spite of the fact that the two countries did not have formal diplomatic ties.” Do I smell a Logan Act violation? You bet I do. You should, too.
