WASHINGTON — Rep. Mark Foley, a Republican from Florida, resigned Friday from the House, a day after a former congressional page questioned e-mails Foley had sent to him.

Foley apparently sent the e-mails in August 2005, when the male page was 16 years old.

“Today I have delivered a letter to the speaker of the House informing him of my decision to resign from the U.S. House of Representatives, effective today. I thank the people of Florida’s 16th Congressional District for giving me the opportunity to serve them for the last twelve years; it has been an honor,” Foley said in a written statement.

“I am deeply sorry and I apologize for letting down my family and the people of Florida I have had the privilege to represent.”

In the e-mails, which were obtained by the Washington-based Citizens for Responsibility and Ethics in Washington, Foley discussed a second page, saying “I just emailed [him]… hes such a nice guy… acts much older than his age… hes in great shape… i am just finished riding my bike on a 25 mile journey now heading to the guy… whats school like for you this year?”

Foley then asked the page for a picture.

The young man, who forwarded the e-mails to another congressional staffer, called the e-mails “sick, sick, sick.”

“Maybe it is just me being paranoid, but seriously. This freaks me out,” the page wrote in the e-mails obtained by CREW.

A spokesman for Foley told CNN the congressman acknowledged he had an e-mail exchange with the former page but flatly denied that it was anything inappropriate.

Speaker Dennis Hastert of Illinois said he supported Foley’s resignation.

“He’s done, as of now; he’s done the right thing,” Hastert said. “I’ve asked John Shimkus, who is the head of the Page board, to look into this issue regarding Congressman Foley. We want to make sure that all of our pages are safe, and the page system is safe.”

“None of us are very happy about it,” Hastert said.

According to GOP sources, Foley is concerned there may be other potential politically damaging e-mails or information out there and has concluded it’s best not to run again for office.

Foley, who is considered a moderate, has been in office for six-terms.

His Democratic opponent in the race, Tim Mahoney, called for an investigation into the matter Thursday. Mahoney’s campaign denied having anything to do with the information getting out.
