Republican businessman John Raese, who appears on the verge of making a real race out of West Virginia's special Senate election, will be in Washington, D.C. next week for a breakfast fundraiser.

Senate Minority Leader Mitch McConnell (R-Ky.) and National Republican Senatorial Committee Chair John Cornyn (Texas) will both attend the event, according to an invitation provided to The Hill. 

Raese faces Gov. Joe Manchin (D-W.Va.) this fall in the special election to fill the remainder of the late Sen. Robert Byrd's (D) Senate seat. 

The PAC fundraiser is set for Tuesday morning at a Capitol Hill restaurant. Individual tickets to the fundraiser go for $500, while the price is set at $1,000 for a PAC and $2,500 to co-host the event.    

Manchin was supposed to be a shoo-in to fill Byrd's seat after Rep. Shelley Moore Capito (R) passed on the race, but new numbers out Monday from Public Policy showed the contest in a dead heat.    

Raese has been largely self-funding his bid against Manchin, pouring more than half a million dollars of his own money into TV ads trying to tie the governor to President Obama and the Democratic leadership in Washington.
