The platform of the Republican Party is set to change for the first time since 2016, setting up a major fight for the future of the conservative movement.

In a memo signed by lead advisers to former President Donald Trump, the campaign explained its goal to shorten the platform “to ensure our policy commitments to the American people are clear, concise and easily digestible.” It continued, “We will present a streamlined platform in line with President Trump’s principled and popular vision for America’s future.”
