He also had a short stint working for a British Member of Parliament, Humfrey Malins, during 2005.

At John McLaughlin's , Rogan was one of the first speakers and maintains a close relationship with the McLaughlin family. In 2017, Rogan joined the Washington Examiner as a commentary writer. In August 2017, a pilot episode of a proposed revival of The McLaughlin Group with Rogan as moderator was taped and published on YouTube. On January 8, 2018, The McLaughlin Group relaunched with Rogan as moderator. In contrast to the previous format in which there were four semi-permanent panelists, the new version features a rotating guest each week. The show aired on WJLA-TV, the local ABC affiliate for the greater Washington, D.C. area, for a few months, then became available online only. After going into hiatus in January 2019, the show returned to the air, with Rogan as moderator and the same format, in September 2019 on Maryland Public Television, which began distribution of the show to PBS stations nationally in January 2020. In November 2019, the show introduced a "Web Exclusive" moderated by Rogan and available online, consisting of additional discussions not included in the weekly television broadcast.
On May 15, 2018 Tom published an article in the newspaper Washington Examiner titled "Ukraine should blow up Putin's Crimea bridge". In his article, Rogan says that the Ukrainian air force should bomb the Crimean Bridge, and that the US should support this. He also claims that the length of the bridge would reduce the number of casualties by those crossing at the time of the attack. The article provoked a strong reaction in Russia, instantly turning the Washington Examiner into the most frequently cited periodical. Many spoke about the article, including the Vice Speaker of the Russian Parliament Irina Yarovaya; and the Russian Embassy to the United States demanded an explanation from Tom Rogan. On 17 May, the Investigative Committee of Russia opened a criminal investigation against Tom Rogan, accusing him of calling for terrorism. Tom Rogan reacted with his new article in Washington Examiner titled "Why Putin wants to send me to the Black Dolphin" and he received support in the editorial "Our response to Russia's threats against our journalists". In the latter it was stated, that Rogan's piece is "an opinion on how one sovereign nation ought to respond to aggression". On May 18, the Investigative Committee opened criminal case against the editor of the Washington Examiner, Hugo Gurdon, too.
