The Washington Post is reporting that Free the Delegates, a group of activists that tried to use party rules to strip Donald Trump of the nomination at the Republican convention, is making another attempt to replace Trump on the ticket:
[Free the Delegates] said Sunday that they’re reaching out to members of the RNC, which includes three representatives from each state, the District of Columbia, Puerto Rico and territories, asking that they sign a petition calling for an emergency meeting that would lead to Trump’s ouster.
Party rules dictate that members from at least 16 states can compel RNC Chairman Reince Priebus to call an emergency meeting, which he would need to convene within 10 days. At the meeting, these activists want RNC members to invoke Rule 9, which lays out how to nominate a new presidential candidate in the event of a resignation, death or other circumstance.
According to the party rulebook, the RNC is authorized and empowered to fill any and all vacancies which may occur by reason of death, declination, or otherwise of the Republican candidate for President of the United States or the Republican candidate for Vice President of the United States. If the nominee is removed, the RNC could opt to hold a new convention or select a new candidate by holding a vote among themselves.
