Ted Cruz successfully defended his Senate seat against Democratic challenger Beto O'Rourke in Texas, allowing Republicans to retain control of the Senate, according to NBC News projections. Cruz's projected win adds to momentum built by Republican Rep. Marsha Blackburn's defeat of Democrat Phil Bredesen in the Tennessee Senate race and Republican Mike Braun's win in Indiana.
