It came after TMZ reported that Trump was considering intervening on behalf of Combs, citing an unnamed source.
The White House official stated Tuesday there was "zero truth" to the report, adding, “The president, not anonymous sources, is the final decider on pardons and commutations."
Combs' lawyers confirmed they asked Trump for a pardon and are planning to appeal his conviction and 50-month prison sentence.
Trump commuted former Republican congressman George Santos’ seven-year prison sentence last week.
