For Yoho there's one plan, and he'll get approximately what I quoted. He's covered by the FERS, as is any Congressman who took office after 1986.
As a former member of Congress, Yoho may be in FRS but accrued benefits at a far higher rate than ordinary federal employees. The average federal employee does not vest a full pension after five years, accessible on retirement at 62. Yoho and other members of Congress have that.
