Trump-style campaigns are set to take place at the Republican National Convention, and the GOP is trying to use the events to build a unified front against what some call a “radical fringe” in the party.

The RNC’s platform and rules committee approved the use of the “extreme right” label as a campaign tactic on Tuesday, a move that would require Republicans to denounce their own candidate.

The move comes after several high-profile conservative voices have called on the party to stop equating the extreme right with white supremacists and neo-Nazis.

They also have expressed concern that the convention could be used as a platform to promote the far right, according to The Associated Press.

The convention, which opens Friday in Cleveland, will have its first day of debate this week.

Republicans are scheduled to nominate a candidate to succeed Trump as the party’s nominee in 2020.
