Fox News host Martha MacCallum concluded her show Tuesday with an emotional tribute to talk radio pioneer Rush Limbaugh to mark his 70th birthday as he continues to battle terminal cancer.

“Before we go tonight, we want to wish Rush Limbaugh a happy 70th birthday today,” MacCallum said on “The Story.”

Limbaugh learned he had Stage IV lung cancer in January 2020, and was awarded the Presidential Medal of Freedom by President Trump at the State of the Union address a month later.

In his final radio broadcast of 2020, Limbaugh thanked his listeners and supporters, revealing at the time that he had outlived his prognosis.

“I wasn’t expected to be alive today,” he said. “I wasn’t expected to make it to October, and then to November, and then to December. And yet, here I am, and today, got some problems, but I’m feeling pretty good today.”

An emotional MacCallum praised the “king of conservative talk radio” for his contributions to “democracy and American thought.”

“We want to say from ‘The Story’ and from me personally, a happy birthday to you, Rush on this 70th birthday.”

Limbaugh is considered one of the most influential media figures of the past 50 years and has played a consequential role in conservative politics since his radio show began in 1988. The program has grown to be the most listened-to radio show in the United States.
