MLB’s sign-stealing scandal could be headed for Congress.U.S. Rep. Bobby Rush, D-Ill., on Friday sent a letter to senior members of the Committee on Energy & Commerce to request an oversight hearing into the cheating scandal that has enveloped MLB in recent days. The committee has oversight over major league sports, Rush’s letter states. “I believe it is our ethical and moral imperative to investigate the Major League Baseball cheat scandal fully and to determine the extent to which this cancer has spread,” Rush writes. “I firmly believe that our investigation must also look at the actions taken by Major League Baseball, and the teams that comprise it, to reprimand the individuals who have been implicated.”RIVERA: MLB must be consistent with punishments for sign-stealingThe letter goes on to say that, although MLB and teams have already taken action against guilty parties — such as Astros manager AJ Hinch and GM Jeff Luhnow — the committee must determine whether league officials acted quickly enough and took appropriate action. It also must determine whether there is a “systematic failure” within MLB that has allowed the illegal sign-stealing problem to fester, the letter states.There was no word Friday evening whether the committee plans to take up Rush’s request.This has been a busy month and week in the life of the scandal. On Monday, Hinch and Luhnow were each suspended for a year — and later fired — as punishment for Houston’s illegal sign-stealing in recent seasons. Fallout from the Astros’ case extended to the Red Sox, who parted ways with manager Alex Cora because of his involvement in Houston’s cheating as a bench coach during the 2017 season; the Red Sox are also under investigation by MLB for alleged cheating in 2018. Ripples also extended to New York, where the Mets and new manager Carlos Beltran ended their relationship before it really began after Beltran was named in MLB’s report on the Astros’ cheating for his actions as a player in 2017.Allegations haven’t been limited to the present. On Friday, former Cy Young winner Jack McDowell told a Charlotte radio station that the White Sox used a camera to steal signs in the 1980s, under the direction of Hall of Fame manager Tony La Russa.This wouldn’t be the first time Congress has gotten involved in a growing MLB scandal. Lawmakers most recently played a role during the steroid era, with 2005 hearings that featured memorable testimony from suspected or admitted PED users including Jose Canseco, Mark McGwire, Sammy Sosa and Rafael Palmeiro. The televised hearings helped shift public opinion on the scandal.
