C-SPAN is asking the Supreme Court to let it broadcast live next spring's arguments over President Barack Obama's health care overhaul.
The not-for-profit network's CEO, Brian Lamb, made the request by letter on Tuesday. There was no immediate response from the justices.
Lamb says the health care arguments will affect "every American's life, our economy and certainly will be an issue in the upcoming presidential campaign."
The Supreme Court has never allowed live audio or video broadcasts. Audio recordings are released on Friday after arguments.
The justices will hear 5 1/2 hours of arguments in March over whether it was constitutional for Congress to require people to buy health insurance or pay a penalty.
C-SPAN, which stands for Cable-Satellite Public Affairs Network, is best known for televising Congress.
