The early afternoon will be filled with procedural remarks, including reports from Republican National Committee Chairman Reince Priebus on convention rules, and candidate presentations by Rep. Pete Sessions (Texas), who chairs the National Republican Congressional Committee.
Boehner will then preside over the roll call of the states, after which Romney and Ryan will be nominated.
Late Monday, the Republican Party reached a procedural agreement that should smooth out the process of nominating Romney. Republicans were considering changes to the rules that would have made it harder for libertarian-leaning Republicans to get delegates to future conventions, but an agreement was reached that essentially ensures that states have the power to select delegates, not presidential candidates.
After a brief recess, Boehner will again call the convention to order at about 7 p.m., which will be followed by a mix of entertainment and political speeches.
Among the speakers expected in the evening are Rep. Cathy McMorris Rodgers (Wash.), Sen. Kelly Ayotte (N.H.), Gov. John Kasich (Ohio), Gov. Mary Fallin (Okla.), Gov. Bob McDonnell (Va.), Gov. Scott Walker (Wis.), Gov. Brian Sandoval (Nev.) and Gov. Nikki Haley (S.C.).
Also up tonight are ex-Sen. and former presidential candidate Rick Santorum (Pa.), and former Rep. Artur Davis (Ala.), who switched to the Republican Party earlier this year.
Tuesday will be closed out with remarks from Ann Romney and New Jersey Gov. Chris Christie. There were some reports that Mitt Romney might join his wife briefly on stage Tuesday night, even though he is due to accept the GOP nomination on Thursday.
