Corker would lead the hearings on Mr. Trump’s nominee for the post.
Would history repeat itself...
"Attempting to forestall a buildup of American forces, Fulbright launched a high-profile series of widely televised public "educational" hearings in February 1966. [The] testimony prompted an angry President Johnson to order FBI director J. Edgar Hoover to investigate whether Fulbright was "either a communist agent or a dupe of the communists.”
Conducted in the Senate Caucus Room, the hearings reached their most dramatic phase when Secretary [of State, Dean] Rusk and General Maxwell Taylor arrived to lay out the administration's case. Fulbright shifted from his earlier role as a benign questioner of supportive witnesses to a grim prosecutor, his dark glasses set resolutely against the glare of television lights.
The February hearings did not immediately erode Senate support for Johnson's war policies. They did, however, begin a significant shift in public opinion."
