Some of Donald Trump’s most trusted aides will travel to Cleveland this week to ensure the plan for the Republican National Convention—an extravaganza where the presumptive nominee will command the nation’s attention for four days—is to their liking.

Trump, a real-estate developer and TV personality who cemented his reputation in the 2016 campaign as a consummate showman, is set to be named the party’s nominee during the nationally televised event in July.

Later this week, aides with the Republican National Committee will give tours and planning updates to several members of Trump’s top staff, including deputy campaign manager Michael Glassner, strategist Paul Manafort, political director Rick Wiley, and Rick Gates, a longtime Manafort associate hired last month, said people familiar with the plans.
