Campbell is a supporter of welcoming refugees and immigrants and building a robust refugee resettlement program. In the Tennessee Senate, she cosponsored the Workforce Expansion Bill, which enables immigrants with work permits to access professional and commercial licenses. She also has vocally opposed anti-refugee and anti-immigrant bills in the state legislature. Heidi believes  Congress has to focus on freedom for families first: That means every hardworking person, small business owner and family farmer has the tools to build a good life – tools like affordable healthcare, childcare, education and energy.
