SANTA ANA PUEBLO, N.M. — The Republican National Committee Friday moved to quell internal opposition to President Trump, overwhelmingly approving a resolution of support for his leadership to demonstrate that potential 2020 primary challengers are unwelcome.

The RNC vote occurred at its annual winter business meeting near Albuquerque. But while the measure affirmed support for Trump and his accomplishments in the White House, it stopped short of expressing support for the president’s renomination to lead the GOP in 2020 and re-election to a second term.
