The Morongo tribe and its card club allies oppose the bill because it would effectively exclude their partner PokerStars.
In a statement, the Morongos said: “We strongly oppose the so-called ‘bad actor’ language that is nothing other than a blatant attempt to provide certain interests with unfair competitive advantage by arbitrarily locking out trusted brands.
“We will vigorously oppose any legislation that includes this language.”
PokerStars remains the largest online poker site in the world and is the subject of a $4.9bn buy-out by the Montreal-based Amaya Gaming.
Whether the acquisition and associated board changes at PokerStars will enable the operator to access US markets from which it has to date been excluded remains to be seen.
Some of the signatories to the Poker bill are well known BAD ACTORS themselves, including the Pechanga Band of Luiseno Indians led by Mark Macarro.
