House Speaker Nancy Pelosi and House Democrats are considering inviting former House Republican Rep. Denver Riggleman to serve as an adviser to the Jan. 6 select committee investigating the Capitol assault, according to sources familiar with the deliberations.

       Riggleman, a former intelligence officer who lost his primary last year, has been a forceful critic of other Republicans over election-related disinformation and QAnon conspiracy theories.
