Thomas Jefferson looks on nervously while Lyndon Johnson “confers” with Sen. Richard Russell (D-Ga.). At 6’4″, Johnson tied Abraham Lincoln as the tallest U.S. president, and he used his physical presence to advance his agenda, cornering his targets in out-of-the-way places and leaning “so close to you,” one staffer recalled, “that your eyeglasses bumped.” In their 1966 book The Exercise of Power, Rowland Evans and Robert Novak dubbed this The Treatment:

The Treatment could last ten minutes or four hours. It came, enveloping its target, at the Johnson Ranch swimming pool, in one of Johnson’s offices, in the Senate cloakroom, on the floor of the Senate itself — wherever Johnson might find a fellow Senator within his reach. Its tone could be supplication, accusation, cajolery, exuberance, scorn, tears, complaint and the hint of threat. It was all of these together. It ran the gamut of human emotions. Its velocity was breathtaking, and it was all in one direction. Interjections from the target were rare. Johnson anticipated them before they could be spoken. He moved in close, his face a scant millimeter from his target, his eyes widening and narrowing, his eyebrows rising and falling. From his pockets poured clippings, memos, statistics. Mimicry, humor, and the genius of analogy made The Treatment an almost hypnotic experience and rendered the target stunned and helpless.

LBJ denied this. “I’d have to be some sort of acrobatic genius to carry it off,” he told an interviewer, “and the senator in question, well, he’d have to be pretty weak and pretty meek to be simply standing there like a paralyzed idiot.”
