The WSJ examines Major League Baseball’s practice of offering lawmakers and officials a chance to buy hard-to-get game tickets.

The league has sold about 75 World Series tickets to a total of 15 lawmakers or aides in the past week, according to Pat Courtney, a spokesman for Major League Baseball. Mr. Courtney declined to identify which lawmakers and aides sought the tickets.

Because the recipients pay for the tickets, the offer complies with ethics rules for Congress and the executive branch. The arrangement, however, highlights what some ethics watchdogs say is a loophole in recently tightened congressional ethics rules, which ban officials from receiving just about any gifts.
