Sam Seder

On January 24, 2019, Seder announced his intention be a candidate in the Libertarian Party primary for the 2020 presidential election as a satirical candidate, due to his opposition to American libertarians.

On April 27, 2018, Seder announced that the couple were separated.

On November 28, 2017, American social media personality, writer, and conspiracy theorist Mike Cernovich published a post on Medium that resurfaced a deleted tweet Seder wrote in 2009 joking about convicted statutory rapist and fugitive film director Roman Polanski. The tweet read, "Don't care re Polanski, but I hope if my daughter is ever raped it is by an older truly talented man w/ a great sense of mise en scene." Cernovich insisted the tweet proved Seder tacitly endorsed Polanski's sex crime. He then approached multiple journalists and news outlets, including MSNBC, to break the story.

The next day, on November 29, 2017, Seder received a voicemail from Cockfield indicating MSNBC's upper management was seriously considering cutting ties with him. Seder responded that MSNBC was making a mistake and that, "there's no story here." Seder further warned Cockfield that if they moved forward with the termination, "You guys are going to be the story." Seder also requested a formal termination email. Seder never received the email, leading him to believe that this employment status was still undecided.

On Sunday, December 3, 2017, Seder was notified by Jon Levine of TheWrap that they had been contacted by MSNBC who had decided to terminate Seder's contract and were about to break the story through their own publication. Seder immediately sent Cockfield an inquiry regarding his status. Cockfield, at first, did not have a status update but later confirmed MSNBC was, in fact, dropping Seder.

The next day, on December 4, 2017, TheWrap announced that MSNBC had severed ties with Seder by not renewing his contract due to the controversial tweet. Seder defended the tweet by pointing out that, taken in context of the current events around the time he posted it, it was a satiric response to a petition urging Polanski's release from detention in Switzerland. An anonymous MSNBC source defended the termination, "It gives us pause when we see alt-right figures whipping up attention about our action but the reality is Seder made a rape joke." After news of the termination broke, Cernovich released a Twitter video celebrating his triumph.

There was considerable dissent within MSNBC over Seder's termination. Some employees expressed concerns that his firing would encourage other far-right personalities to launch similar smear campaigns. A senior MSNBC employee characterized the capitulation as "really weak" and "pathetic". MSNBC's management itself was unsettled by the celebratory reaction from the far-right. On December 7, 2017, MSNBC decided to reverse their decision to terminate Seder's employment. MSNBC President Phil Griffin said in a statement, "Sometimes you just get one wrong, and that's what happened here. We made our initial decision for the right reasons—because we don't consider rape to be a funny topic to be joked about. But we've heard the feedback, and we understand the point Sam was trying to make in that tweet was actually in line with our values, even though the language was not. Sam will be welcome on our air going forward." In response, Seder issued a statement while accepting his job back:

In November 2010, Seder began an independent online podcast, also called The Majority Report. The live talk-show format closely matches the previous Air America program, with politically-oriented commentary by Seder and co-hosts and interviews with various guests. Seder offers listeners different tiered levels of access to content around the show via crowdfunding platform Patreon.

In late 2010, Seder began occasionally serving as substitute host of Countdown with Keith Olbermann when Olbermann was on vacation. In December 2010, Seder also became co-host of the nationally syndicated progressive radio interview program Ring of Fire, co-hosted by Robert F. Kennedy Jr. and Florida-based attorney Mike Papantonio.

In November 2009, Seder hosted a pilot for NBC of an American version of Have I Got News for You. Three years later, in November 2012, it was announced Seder would again be the host of an American version of the show, this time on TBS.

Seder noted that advertisers on The Majority Report with Sam Seder podcast were also being contacted and pressured by Cernovich and his team to cut ties with the show over the tweet. In response, Seder launched a GoFundMe campaign to help maintain funding for the show in the face of potential loss of advertising revenue. In an episode of the podcast titled, "I'm Under Attack By the Nazi Alt-Right", Seder said, "this smear involves the willful misinterpretation of a tweet that I posted in 2009" and that he will "never be ashamed of criticizing those who would excuse the predation of women or girls."

Seder also occasionally substituted for Randi Rhodes when Rhodes was on Air America, as well as Mike Malloy on The Mike Malloy Show on the Nova M Radio network. In 2008 he also began a collaboration with Marc Maron on Maron v. Seder, an hour-long video webcast. In January 2009, Maron v. Seder was renamed Breakroom Live with Maron & Seder and aired live from the kitchen in the Air America offices weekdays. Seder and Maron also hosted a post-show chat with viewers after each episode. Air America Media cancelled Breakroom Live with Maron & Seder in July 2009. In 2010, Air America was shut down.

During Mark J. Green's restructuring plan to transform Air America into a profitable leader in progressive talk radio, called "Air America 2.0", The Sam Seder Show was cancelled on April 13, 2007 and replaced by WOR Radio Network late night radio show host Lionel. Seder was relegated to a Sunday show entitled Seder on Sunday. Lionel soon lost two-thirds of Seder's live affiliates and listenership. The final Seder on Sunday was broadcast on June 1, 2008.

On August 9, 2005, Seder's then-wife gave birth to a daughter. On March 7, 2013, she gave birth to their second child, a son.

In March 2004, Seder became co-host of Air America Radio's The Majority Report alongside Janeane Garofalo.

On September 1, 2004, Seder was briefly detained by the United States Secret Service during his live, on-site coverage of the Republican National Convention at Madison Square Garden. Shortly after Zell Miller gave his speech, Seder began searching (with a sign in hand) on the convention floor for a willing homosexual Republican to interview live on radio. Shortly thereafter, he was physically removed from the floor and – after brief questioning – asked to leave the convention. Seder later commented that his wearing of a lapel pin that he had been given by a Secret Service agent at the Democratic National Convention earlier that year had kept him from being ejected from the convention completely.
