Senator Ted Cruz is doubling down on his attack of Mark Cuban and the NBA -- claiming the league SAYS it's all about social justice ... until it comes to China.
"When it comes to communist China, [the NBA makes] a crap ton of money from China so they silence everybody," Cruz said ... "They're not willing to say a word."
Cruz is referring to the NBA's 2019 dust up with China -- when the country blackballed the league because Houston Rockets GM Daryl Morey dared to tweet support for protestors in Hong Kong.
