Warren also warned against dismissing Kid Rock's potential bid.
He also blessed his Facebook followers with two music videos - for the songs, "Greatest Show on Earth" and "Po-Dunk" - noting that he planned to release new music while stumping for office, much like other politicians write books from the campaign trail.
While it's unclear exactly where exactly Kid Rock's political loyalties lay, his large fanbase in Trump country and personal friendship with the 45th president suggest he would run a populist campaign closely aligned to Trump's political movement.
Robert James Ritchie, known professionally as Kid Rock, announced his candidacy last week for the U.S. Senate seat now held by Michigan Democrat Debbie Stabenow.
It was not immediately clear under which political Party Rock might launch his Senate candidacy.More news: Walmart apologizes for racial slur in product description for weaving cap
The singer - whose real name is Robert Ritchie - is considered by many a fiscally conservative but socially liberal Republican.
In February, news reports claimed that GOP officials in MI were considering asking the rapper to run against the state's Democratic incumbent, Sen.
"Look, Trump won Debbie's state of Michigan, so we can't just laugh this off or make assumptions", reads the email, which raises money for both Hassan and Democratic Michigan Sen.
The news was first reported in the Boston Herald. So far this year, the rapper has yet to announce any new records.
His take? "I concede she is better at playing politics than I am, so I'll keep doing what I do best, which is being a voice for tax paying, hardworking AMERICANS", said Rock, who hasn't kept his Trump-supporting ideology under wraps.
