USA TODAY Sports Olympics reporter Nicole Auerbach is joined on the telephone by USAT sports editor David Meeks to dive into the ever-changing story of U.S. swimmer Ryan Lochte and his three Olympic teammates and their encounter with Brazilian security guards at a gas station in Rio de Janeiro.

David offers the latest findings in the investigation, which tilt the story toward the possibility that Brazilian police, like Lochte, might have embellished their story.

The pair also discuss how Lochte was dropped from sponsors, how the media, in general, covered this story all wrong, and how the Rio Games should not be remembered mostly for this non-Games-related altercation.

The story by Meeks and Taylor Barnes can be read at: http://www.usatoday.com/story/sports/olympics/rio-2016/2016/08/21/investigation-ryan-lochte-rio-olympics-authorities/89082232.

USA TODAY Sports' Nicole Auerbach and Sam Amick recap the overall performance by Michael Phelps and USA Swimming at the 2016 Rio Olympic Games.

Phelps walks away with five gold medals and one silver, to run his career-best tally to 28 total Olympic medals -- 23 gold. He displayed raw emotion and appreciation and says retirement is next, as he's in a much better place than he was four years ago in London. But is this REALLY it?

It was also a record-breaking Olympics for Katie Ledecky, and breakout stars Lilly King, Maya Dirado, Ryan Murphy and Simone Manuel helped make the Rio Games a real pool party for the Americans.

Then USA Swimming coach Bob Bowman joins Nicole at the end of this episode to discuss all things Michael Phelps -- past, present and future.

USA TODAY Sports columnist Nancy Armour and Olympics reporter Rachel Axon discuss the IOC delegating decisions about Russian athlete eligibility to international sports federations rather than banning the country for running a state-sponsored doping program. The decision leaves plenty to be answered as 27 federations must decide on the eligibility of hundreds of Russian athletes before the Games open on Aug. 5, and Nancy and Rachel discuss what will come as a result of the IOC’s decision.
