Six Los Angeles-area members of Congress added their voices to the Dodgers television issue Monday, appealing to Time Warner Cable, DirecTV and other providers to enter into binding arbitration to resolve the dispute and show the team's games on all L.A.-area cable and satellite systems. Congressman Brad Sherman (D-Sherman Oaks) made available to the Los Angeles News Group a letter he sent to DirecTV CEO Michael White and Time Warner CEO Robert Marcus.
