Graphic allegations of "sexually charged" conduct rocking a federal agency have attracted the attention of Congress, with Republican Rep. Michael McCaul launching an inquiry this week into the charges. 

FoxNews.com has learned that McCaul, R-Texas, whose subcommittee oversees the Department of Homeland Security, reached out to the attorney in a recent lawsuit against DHS to begin probing the claims about conduct at Immigration and Customs Enforcement. 

"The investigation I'm sure will be all-encompassing," spokesman Mike Rosen said. "(McCaul) believes it's kind of a culture (at DHS) that's grown over there over -- I don't know how long -- a culture that is, unfortunately ... I guess in some ways it's become an incubator for corruption, for misconduct, for waste." 

McCaul is chairman of the Subcommittee on Oversight, Investigations and Management for the Homeland Security Committee.
