As polls show his race tightening, U.S. Sen. Ted Cruz is lashing out at national Republicans for not doing more to help him in his battle against Democrat Colin Allred.

Cruz told Fox News he’s being massively outspent by Allred on the airwaves and couldn’t even afford to get his own ads on TV until three weeks ago. And he complained U.S. Senate Republican Leader Mitch McConnell hasn’t spent a penny on the race even though his PAC, the Senate Leadership Fund, is sitting on millions of dollars meant to fight for a GOP majority.
