Oleg Aleksandrovich Prudius (Russian: Oleg Aleksandrovich Prudius; Ukrainian: Oleg Oleksandrovich Prudius, Oleh Oleksandrovych Prudius; born April 27, 1979) better known by his ring name Vladimir Kozlov, is a Ukrainian-American producer and retired professional wrestler. He is best known for his time in WWE, where he won the WWE Tag Team Championship once with Santino Marella. He is trained in freestyle wrestling, rugby, football, sambo, kickboxing, judo, jujutsu, Brazilian jiu-jitsu and mixed martial arts. Prudius has also worked as a stage and screen actor, notably having a small role in Spike Lee's 25th Hour., and a walk-on role in the second season of the HBO series The Wire.
On April 13, 2009, Kozlov was drafted to the ECW brand as part of the 2009 WWE draft, as ECW's only pick of the night. Shortly after the draft, his character was tweaked to further highlight the training he received within the Russian military. He won his first match on the brand when he easily defeated a local competitor. On the June 30 episode of ECW on Syfy, he teamed with William Regal to defeat Christian and Tommy Dreamer. His first defeat in singles competition on ECW came on the July 9 episode of ECW, where he lost a #1 contenders match to Christian for Tommy Dreamer's ECW Championship at Night of Champions.  On July 21, Kozlov began an angle with Ezekiel Jackson in which, week after week, after one of them had easily defeated a local competitor, the other would come out and execute their finishing move on the fallen opponent in a game of one-upmanship. On the August 18 episode of ECW, Jackson was set to team with ECW Champion Christian against the team of Kozlov and number-one contender William Regal. Jackson turned on Christian, forming an alliance with Regal and Kozlov. Kozlov and Jackson aided Regal in his feud with Christian over the ECW Championship, but Regal was unable to capture the title.  On the December 15 episode of ECW, Kozlov came out with Regal to face Jackson in an ECW Homecoming battle royal qualifying match. During the match, Regal turned on Kozlov by pulling his feet while at ringside, which ultimately cost him the match. After the match, Kozlov attempted to attack Regal, but Jackson jumped him from behind and both proceeded to attack Kozlov. This split Kozlov from the Ruthless Roundtable, making him a face character.

Breitbart was born in Los Angeles, California, on February 1, 1969. He was the adopted son of Gerald and Arlene Breitbart, a restaurant owner and banker respectively, and grew up in the affluent neighborhood of Brentwood, Los Angeles. He was adopted at three weeks old and raised Jewish. His biological parents had been Irish American.
Breitbart has been lauded for his role in the "evolution of pioneering websites" including The Huffington Post and The Drudge Report, and more recently his "Big" sites. Journalists such as Nick Gillespie and Conor Friedersdorf have credited Breitbart with bringing new voices to debates about politics and culture. Breitbart told Reason in 2004 that after feeling ignored by existing outlets, "We decided to go out and create our media." Described as "a series of do-it-yourself demonstration projects" and "conversation pits", the Breitbart.com websites have been both criticized and praised for their role in various political issues. Breitbart has been recognized for adopting an inclusive stance with regard to LGBT participation in the conservative movement. He has also been credited with helping to derail conspiracy theories about Barack Obama's citizenship.  In 1995, Breitbart saw The Drudge Report and was so impressed that he e-mailed Matt Drudge. Breitbart said, "I thought what he was doing was by far the coolest thing on the Internet. And I still do." Breitbart described himself as "Matt Drudge's bitch" and selected and posted links to other news wire sources. Later, Drudge introduced him to Arianna Huffington (when she was still a Republican) and Breitbart subsequently assisted in the creation of The Huffington Post.  Breitbart wrote a weekly column for The Washington Times, which also appeared at Real Clear Politics. Breitbart also co-wrote the book Hollywood, Interrupted: Insanity Chic in Babylon with Mark Ebner, a book that is highly critical of U.S. celebrity culture. On January 19, 2011, the conservative gay rights group GOProud announced Breitbart had joined its Advisory Council.  In April 2011, Grand Central Publishing released Breitbart's book Righteous Indignation: Excuse Me While I Save the World, in which he discussed his own political evolution and the part he took in the rise of new media, most notably at the Drudge Report and The Huffington Post.  In June 2011, Breitbart's websites broke the story that congressman Anthony Weiner was sending women revealing photographs of himself.
