Two House Democrats are urging Major League Baseball and the players union for implementing testing for human growth hormone and ban chewing tobacco by players in uniform and in public view.

Reps. Henry Waxman of California and Frank Pallone of New Jersey made those requests in a letter to Commissioner Bud Selig and Michael Weiner, executive director of the players union.

“The time to begin testing for HGH in baseball has arrived,” Waxman wrote, citing the use of blood testing for HGH in the Olympics.
