US swimmer Jack Conger tweets "Free Ryan Lochte;" Gunnar Bentz takes his Twitter private

U.S. Swim Team members Gunnar Bentz and Jack Conger are both back in the country after being detailed by Rio authorities following a "robbery" report that turned out to be a feud at a gas station bathroom. The University of Georgia's Bentz has taken his Twitter feed private while the University of Texas' Conger is using his to celebrate their return, defend his teammates and spar with followers. "Free Ryan Lochte and Jimmy Feigen," he posted.

Gunnar and Bentz arrived at Miami International Airport about 6:30 a.m., having been detained in Rio while authorities launched an exhaustive investigation following teammate Ryan Lochte's report they had been robbed. The head of the U.S. Olympic Committee issued a lengthy statement Thursday night, apologizing to "our hosts in Rio and the people of Brazil for this distracting ordeal" and saying the athletes would face a review by the USOC.

Lochte had already returned to the United States when authorities issued an order for him to stay in the country while they investigated the robbery claim. At a lengthy news conference on Thursday, Rio authorities said the investigation continues but that for now, they are saying no robbery took place.

Meanwhile TMZ posted a report that says "Lochte did not lie about the 'robbery' incident … and there are three minutes of missing surveillance video that will back up most of his story."

"Lochte mistook the uniforms worn by the security guards as police uniforms, and he claims during the missing three minutes he and the other swimmers were pulled out of the taxi at gunpoint," TMZ continued. "(Fellow swimmer) Jimmy Feigen just spoke with local news in San Antonio, denying a cover-up and affirming he was robbed."

Bentz' Twitter feed, which included a cute photo of him and his alma mater's mascot, is now private.

Conger's feed is still active. In recent posts he's written a message of support for teammates Lochte and Jimmy Feigen, told a follower who thought he looked scared in Rio to "stop spreading lies" and admonished another who thought the swimmers should have their medals taken away.
