The millionaire real estate developer won Tuesday's special election over Democrat Archie Parnell in the 5th District, which stretches north from Columbia toward the suburbs of Charlotte, North Carolina.
Norman, a former state lawmaker, ran a campaign aligning himself with President Donald Trump, who won this district in November by more than 18 percentage points. He emerged as the top vote-getter from a seven-way GOP primary and defeated state lawmaker Tommy Pope by just more than 200 votes in a runoff.
Parnell, a former Goldman Sachs tax adviser, had argued he was best suited to represent the district, which was in Democratic hands for more than 100 years until Mulvaney's 2010 victory.
