Yes. Why then, did they lie about it if the basis for their interest was as innocent as you describe? I think we all can agree that Oswald's visit to the Soviet Union should have raised alarm bells at the CIA and FBI. If that's all there was to it, there's no sense in lying about it or keeping secrets about it decades later.
Banksie,
Please freshen my memory -- How, exactly, did James Angleton "lie" about his interest in Oswald?
Regardless, JFKA conspiracy theorist John M. Newman (author of the 1995/2008 book, "Oswald and the CIA"), who used to think James Angleton was the mastermind of the JFKA, now says in his 2022 book, "Uncovering Popov's Mole," that a KGB mole by the name of Bruce Leonard Solie sent (or duped his confidant, protégé, and mole-hunting subordinate, Angleton, into sending) Oswald to Moscow in 1959 as an ostensible "dangle" in a (unbeknownst to Angleton and Oswald) planned-to-fail hunt for "Popov's Mole" / "Popov's U-2 Mole" (Solie) in the wrong part of the CIA -- the Soviet Russia Division -- which mole hunt lasted nine years, tore the SRD apart, and drove Angleton nuts.
Factoid: Newman dedicated his book to the aforementioned CIA good-guy, Tennent H. Bagley (look him up).
