Trump expected to make appearance every night of RNC this week

Trump campaign senior adviser Jason Miller on Sunday told NBC's "Meet the Press" that viewers can plan on hearing Trump "speaking at various parts through each of the nights" at the GOP convention, but would not elaborate whether that meant live remarks, speeches or prerecorded video segments.

Miller said Republicans will present an "optimistic and upbeat convention this week" in contrast with what he described as last week's "massive grievance fest" of a Democratic National Convention.

The RNC will focus heavily on Trump's accomplishments over his first four years, lay out a second term vision for the administration, and promised "a complete change in the perception that I believe the media tries to tell of what a Trump supporter looks like, or who a Trump supporter is," Miller added.

The convention will also feature "breakout stars," people one wouldn't typically consider to be Trump supporters, and "a great, uplifting message from the President," he told NBC.

Dan Scavino, one of President Donald Trump's longest serving aides and one of the few people with access to his Twitter account, is scheduled to speak at the RNC this week, a person familiar with the planning told CNN.

As the deputy chief of staff for communications, Scavino is in a public-facing role, but he rarely speaks publicly.

Trump and Vice President Mike Pence are expected to make an appearance at the Republican National Convention in Charlotte, North Carolina, on Monday, a Republican official familiar with the plans confirmed to CNN.

Trump and Pence are expected to attend the roll call votes by the slimmed-down group of 336 RNC delegates who will formally nominate Trump and Pence as the 2020 Republican presidential and vice presidential nominees. Because North Carolina would not give permission for a large scale event, Republicans decided not to hold the rest of their convention there.

Trump is expected to give brief remarks to the delegates, but his formal acceptance speech will happen remotely Thursday from the White House.

The White House announced Saturday the President would be going to Charlotte as part of a day-long series of events in North and South Carolina. The White House and reelection campaign have refused to divulge any details of Trump's visit since first reports of the stop emerged Friday.

A White House advisory only says the President will arrive at 11:45 a.m., Monday in Charlotte.

The New York Times first reported Trump's expected attendance at the roll call, which also noted this will be the only in-person portion of either party's quadrennial gathering.

Trump, a television producer at heart, is hoping for a convention next week that looks vastly different from the all-digital event Democrats have staged over the past days -- including an emphasis on live programming and at least some type of audience who can respond to the multiple appearances he is planning.

The convention ordered up by the President is expected to contain moments that are designed both to surprise viewers and trigger outrage from Trump's opponents. Details for the week remain fluid and some of the central elements were still being worked out between the White House, Republican National Committee and convention planners. Trump's aides were reaching out to potential participants, including a long slate of Americans whose personal stories they believe will resonate with voters.
