Who is Katie Britt, the senator who delivered the Republican State of the Union response?

Alabama Sen. Katie Britt, selected by Republican leaders to deliver the response Thursday night to President Biden's State of the Union address, offered a dark vision of America under his presidency and sought to portray him as old and out of touch with the needs of everyday Americans.

Britt, who is 42, was elected as the junior senator from Alabama in 2022, winning the seat left open by former Sen. Richard Shelby. She ran against Rep. Mo Brooks in the Republican primary runoff, and initially, former President Donald Trump endorsed Brooks. Later, however, he withdrew his support when polls showed Brooks trailing. Trump endorsed Britt months later, after she had received the most votes in the primary and advanced to a runoff against Brooks.
