Bryon moved from farming into insurance, managing an agency from 2003 and buying it in 2010 as Noem Insurance. Kristi rose from the state legislature to the U.S. House and was sworn in as South Dakota's governor on January 5, 2019. Around 2019 she was linked in reports to Corey Lewandowski; photos and media stories prompted denials from both, and The Wall Street Journal reported on the speculation.
On March 5, 2026, Donald Trump announced Kristi Noem would be replaced as Homeland Security secretary, naming Markwayne Mullin effective March 31. After the firing, gossip columns said Lewandowski ended the relationship; Bryon stood with Kristi during subsequent congressional hearings, where she dismissed the claims as tabloid material while senators pressed for a clearer on-the-record denial.
