The Republican presidential candidate who has filed 27 of at least 40 cases pending across the nation seeking to disqualify former President Donald Trump from the 2024 presidential primary ballot had a conversation with Law.com to explain his motivation, legal strategy and what comes next.

John Anthony Castro, a lesser-known candidate seeking the nomination to the Republican primary ballot, filed his first lawsuit a little more than a year ago on the anniversary of the Jan. 6, 2021, attack on the U.S. Capitol. Since then, he has filed 27 new pro se suits in federal courts across the country seeking to prevent Trump from appearing on primary ballots based on the insurrection clause in Section 3 of the Fourteenth Amendment.
