Rand Paul appears to have finalized plans for his presidential campaign announcement and at least part of his subsequent rollout, according to invites posted by his political committee RAND PAC to the website Eventbrite.

As previously reported, the Kentucky senator plans to announce his bid for president April 7 at the Galt House Hotel in Louisville. The invitation posted online urges supporters to "join Senator Rand Paul for a very special rally."

"You won't want to miss this historic event," the invitation adds. The event, not billed explicitly as the official launch to Paul's campaign, is set to begin at 11:30 a.m.

Paul's committee has also posted invites to two events following his announcement in Louisville, likely part of Paul's official campaign rollout. The first, on April 9, will be a rally at the U.S.S. Yorktown in Mt. Pleasant, S.C. Paul will then travel April 10 to the University of Iowa in Iowa City for a rally in the student union ballroom.

The same account, which is linked to Paul's Facebook and Twitter, also posted an event invite for a Twitter Q&A by Paul during the SXSW conference in Austin earlier this month. A senior aide to Paul did not respond to an email asking to confirm the authenticity of the invites.

Unlike Sen. Ted Cruz, who held his official campaign launch at Liberty University, during an event where student attendance was mandatory, Paul will need to attract supporters to turn out to his campaign announcement in Louisville and the subsequent events in key primary states — a process likely made easier with online invitations.
