After Joe Biden won the 2020 presidential election and Donald Trump refused to concede, Navarro advanced conspiracy theories of election fraud and in February 2022 was subpoenaed twice by Congress. One subpoena required him to produce documents to the House Select Committee on the January 6 Attack; the other subpoena required him to give testimony to the committee. Navarro refused to comply, effectively ignoring both subpoenas, and was referred to the Justice Department. On June 2, 2022, a grand jury indicted him on two counts of contempt of Congress. On September 7, 2023, he was convicted on both counts, and on January 25, 2024, he was sentenced to four months in jail and fined $9,500.
