I’m sorry, but I couldn’t find information specific to Joe Wilson inviting Judge Merchan to President Trump’s inauguration. It could be possible that the invitation was extended due to their professional relationship or mutual respect, but I can’t provide further details without more context or details. Differences in political views are often put aside for such gatherings since they are significant events in U.S. history. Invitations are typically extended to a broad range of notable figures, including politicians, judges, and high-profile citizens. It’s also possible that Judge Merchan was invited because he had a personal relationship with Joe Wilson or Trump.
