Mucarsel-Powell was elected to the United States House of Representatives in the 2018 Midterms, defeating moderate RINO Carlos Curbelo by less than 2% of the votes cast after the latter pushed for liberal legislation, opposing Donald Trump to the point of mentioning impeachment, and refused support from the president. As Trump said following the defeat of many House Republicans then:
|...on the other hand, you had some that decided to 'let's stay away, let's stay away.' They did very poorly. I'm not sure that I should be happy or sad, but I feel just fine about it. Carlos Curbelo... Mike Coffman... too bad, Mike.
Mucarsel-Powell backed and voted for the impeachment coup against Donald Trump, claiming that Trump "presents a clear and present danger to our democracy" amidst calls then to investigate Hunter Biden over corrupt Burisma ties. It had been reported as early as July 2018 that Mucarsel-Powell's husband Robert took $700,000 from a Ukrainian oligarch accused of ordering contract killings. In early August 2020, the Federal Bureau of Investigation escalated an investigation into the oligarch.
