Source: Fox News host Laura Ingraham had to backtrack after mistakenly mixing up Nicki Minaj with her longtime rap rival and resident WAPtivist Cardi B on air, a mix-up critics are copiously cackling over. The hilarious on-air blunder occurred as the two discussed Nicki's appearance at the President's Trump Accounts Summit on Wednesday, where she declared herself the controversial Republican's "No 1. Fan," and reportedly donated between $150,000 and $300,000 to support his Trump Accounts initiative-individual retirement accounts designed to encourage early wealth-building, CNBC noted.
