Two new allegations are on the table about the Cartagena Secret Service prostitution scandal of 2012 - was an independent investigation delayed or watered down to protect the White House and was a White House volunteer in Colombia shielded from scrutiny?
The Washington Post says the Obama administration knew of allegations that a White House volunteer brought a prostitute to his hotel room on that trip.
As CBS News' Major Garrett reports, the Obama White House denies a cover-up of the Cartagena scandal, especially the charge leveled by government investigator David Nieland that political pressure hobbled the prostitution probe.
An associate of Nieland's, Gregory Stokes, raised the charge in 2013 with former CBS News correspondent John Miller.
"A man of high integrity in my opinion, was placed on administrative leave for refusing to redact or omit portions of his original report to the satisfaction of the inspector general," Stokes said.
