Trump and Romney have clashed on numerous occasions.

Trump has criticized Romney repeatedly in recent months after the Utah senator was the only Senate Republican to break from his party and vote with Democrats to convict Trump on a charge of abuse of power following Trump's Senate impeachment trial.

Paul is the first senator to announce he tested positive for COVID-19.

Trump told reporters it's "been a long time" since he had in-person contact with Paul.
