U.S. House Speaker John Boehner, R-Ohio, is set to visit Fairview Heights on Monday morning for a $250-per-plate fundraising event on behalf Jason Plummer, the GOP nominee for the 12th U.S. House District seat.

Boehner is coming to town for a "breakfast briefing" with tickets selling for $2,500 per table, according to an email alert the Plummer campaign sent to supporters.

The event is set to begin at 10:30 a.m. at the Four Points Sheraton Conference Center, 319 Fountains Parkway, according to a flier for the event. Details have not been officially released by the Boehner camp, according to Plummer's campaign staff.

"This is a national security issue here," said Deb Detmers, Plummer's campaign manager. "So we just don't do anything that we are told by the speaker's office not to release."

Boehner visited the Chicago area Thursday to take part in fundraising events for House GOP members Judy Bigert and Bob Dold, the Chicago Tribune reported Thursday.

Also on Monday, Boehner is set to host a fundraiser for U.S. Rep. Bobby Schilling, R-Moline.

The Democratic Congressional Campaign Committee welcomed Boehner to Illinois with a blitz of radio ads and robo-calls playing on concerns that GOP budget plans will cut entitlement programs for the elderly and cut taxes for the wealthy.

"The DCCC will run radio ads about Congressman Bobby Schilling and millionaire candidate Jason Plummer ... to hold them accountable for standing with Speaker Boehner and millionaires instead of fighting for middle class families in Illinois," according to the committee's statement.

Plummer, 30, is vying with Democratic nominee Bill Enyart, 62, of Belleville, and Paula Bradshaw, 59, of Carbondale, to replace U.S. Rep. Jerry Costello, D-Belleville, who is retiring after 24 years in office.

Bradshaw said Boehner's scheduled appearance on Plummer's behalf will hurt him, since "Boeher's too right wing. I think most people in this district are not quite that right wing."

Boehner's appearance at a $2,500-per-table fundraiser for Plummer "clearly shows where Jason Plummer and his allies' priorities are," said Jason Bresler, Enyart's campaign manager. "It clearly is not with the majority of the working class in District 12."
