New House Speaker Paul Ryan was quick to remove the portrait of disgraced lawmaker Dennis Hastert from the speaker's lobby outside the U.S. House of Representatives floor.

But Ryan won't be unloading nine donations he received from Hastert over the years.

From 1998 to 2012, Hastert gave $25,500 to Ryan's campaign fund through his leadership fund, Keep Our Majority PAC, records show. Hastert, an Illinois Republican, served as House speaker from 1999 to 2007.

Susan Jacobson, campaign manager and finance director for Ryan, said last week that the Janesville Republican would not be returning the cash.

"Those contributions both came in and were spent many years ago," Jacobson said.

Scot Ross, head of the liberal group One Wisconsin Now, suggested that Ryan give the money to charity. U.S. Sen. Mark Kirk, an Illinois Republican, announced in June that would give a $10,000 Hastert donation to a nonprofit that helps provide after-school programs for children.

"Paul Ryan raised nearly $3 million in 2015 alone, so giving Hastert's $25,000 to charity should be no problem," Ross said.

Hastert's leadership fund also gave one $1,000 donation each in 2012 to U.S. Reps. Reid Ribble and Sean Duffy, both Wisconsin Republicans. Neither has said if he plans to dump the donation.

Last month, Hastert pleaded guilty to one count of dodging bank rules to hide $3.5 million in hush money he paid to try to cover up allegations that he sexually assaulted a former student while he was a high school wrestling coach decades ago.

Prosecutors have recommended Hastert, the longest serving GOP speaker of the House, serve up to six months behind bars. Sentencing is set for Feb. 29.
