The Republican National Committee won’t take up any rule changes governing presidential nominations during their winter meeting, despite calls from some Trump supporters to protect the president from a primary challenge in 2020.

In a late Friday email, the chairman of the standing committee on rules, Jeff Kent of Washington state, alerted RNC members that no rules changes would be undertaken when RNC members gather for their annual winter meeting in New Mexico. Instead, he said any possible changes would have to wait until next year.
