New Speaker of the House JOHN BOEHNER is embroiled in a bombshell sex scandal – involving at least two different women, The ENQUIRER has learned!

Capitol Hill insiders and political bloggers have been buzzing about an upcoming New York Times probe – detailing an alleged affair that the 61-year-old married father of two had with pretty Washington lobbyist LISBETH LYONS.

And an ENQUIRER investigation has uncovered a bedroom encounter that Boehner – second in line of succession to the presidency – allegedly had with LEIGH LaMORA, a 46-year-old former press secretary to ex-Colorado Congressman JOEL HEFLEY.

The Ohio native, a congressman for 20 years, and his wife Deborah, 62, have been married for 37 years.

But she has shunned the capital’s social scene, and he is often seen out on the town without her.

"Deborah normally stays back in Ohio while John spends most of his time in D.C.," said an insider. "It is not uncommon for Boehner to attend parties and events without his wife."

Contacted by The ENQUIRER in late January about the cheating charges, Deborah stood by her man and would not comment about the explosive allegations.

But The ENQUIRER learned that Deborah was nowhere to be seen when the ruggedly handsome congressman attended a casino party at the home of a D.C. lobbyist in August 1997 – and reportedly hooked up with pretty congressional press secretary Leigh LaMora.
