John M. Newman says in his 2022 book,
Uncovering Popov's Mole, that Bruce Solie, James Angleton's confidant, mentor, and mole-hunting superior in the Office of Security, was a KGB "mole," and that he betrayed CIA's spy, GRU Lt. Col. Pyotr Popov, to Yuri Nosenko's ostensible boss, Vladislav Kovshuk, in Washington, D.C., movie houses in January 1957.
He says that when Popov's handler in West Berlin, Russia-born (probable mole, imho) George Kisevalter, sent a cable to CIA headquarters in April 1958 saying that Popov told him that he'd overheard a drunken GRU colonel boast at a New Year's Eve party that the Kremlin had all of the specifications of the U-2 spy plane, Solie decided to send Oswald to Moscow as an ostensible "dangle" in a (unbeknownst to Angleton and Oswald) planned-to-fail hunt for "Popov's U-2 Mole" (Solie) in the wrong part of the CIA -- the Soviet Russia Division.
Which mole hunt lasted nine years, protected Solie from being uncovered, tore the Soviet Russia Division apart, and drove Angleton nuts.
We know that in the interest of "source protection," Popov wasn't secretly arrested and "played back" against the CIA until November 1958, and that he was publicly arrested on 16 October 1959, the same day that Oswald arrived in Moscow.
