Following former President Trump's decisive victory over former South Carolina Governor Nikki Haley in the New Hampshire Primary, many Republicans called for the party to unite and focus on the general election against President Biden. One of those Republicans was Kansas Senator Roger Marshall. He thinks the GOP needs to stop fighting among itself and work to put an end to what he sees as the Biden Administration's harmful policies on the border and the economy. Sen. Marshall joined host Dave Anthony on the Rundown to discuss his support for Trump, the border crisis, and what he hopes a potential bipartisan immigration bill should look like. The Kansas Senator, who is a physician as well, also weighed in on the ongoing investigation into the origins of COVID and what he thinks the American people will learn as Dr. Anthony Fauci, former Director at the National Institutes of Allergy and Infectious Diseases (NIAID), and other health officials from that period continue to get scrutinized by Congress. We made edits for time and thought you might like to hear our entire conversation with Kansas Senator Roger Marshall. On today's FOX News Rundown Extra, you'll hear even more of his take on the 2024 presidential race, the border crisis, and what he sees as a cover-up surrounding the origins of COVID-19.
