Sean Patrick Hannity was born in New York City, New York, the son of Lillian (Flynn) and Hugh Hannity. Lillian worked as a stenographer and a corrections officer at a county jail, while Hugh was a family-court officer. He is the youngest of four siblings. All of his grandparents immigrated to the United States from Ireland.
Candidacy of Donald Trump
Hannity is notable for his pro-Trump coverage. According to the Washington Post, "Hannity's comeback coincided with his early, eager embrace of his fellow New Yorker... Trump attacked the Gold Star father, and Hannity stood by him. Trump went after a federal judge of Mexican descent, and Hannity backed him. Even after the "Access Hollywood" tape emerged of Trump boasting about grabbing women, Hannity defended his guy: "King David had 500 concubines, for crying out loud." After the inauguration, the first interview the new president gave to a cable news channel went to Hannity." Hannity also defended the Trump administration's false claim that Trump's inauguration crowd was the biggest ever.  Hannity was criticized by some, especially supporters of Ted Cruz's 2016 presidential campaign, as being overly favorable to the candidacy of Donald Trump and granting Trump more airtime than other presidential candidates during the 2016 primaries. Hannity, for instance, let Donald Trump promote the false conspiracy theory that Ted Cruz's father was involved in the John F Kennedy assassination. During interviews, Hannity "frequently cites areas where he agrees with Trump, or where he thinks Trump was right about something, then asks him to expand on it", and "often ignores or defends Trump from criticism," according to a CNN report. Tensions between Cruz and Hannity appeared to reach a boiling point during a contentious April 2016 radio interview, during which Cruz implied Hannity was a "hard-core Donald Trump supporter" and Hannity responded by accusing Cruz of "throw[ing] this in my face" every time he asked a "legitimate question". Jim Rutenberg reported in August 2016 that Hannity is "not only Mr. Trump's biggest media booster; he also veers into the role of adviser," citing sources who said Hannity spent months offering suggestions to Trump and his campaign on strategy and messaging. Hannity responded to the report by saying, "I'm not hiding the fact that I want Donald Trump to be the next President of the United States. ...I never claimed to be a journalist." (In an article published in December 2017, Hannity said "I'm a journalist. But I'm an advocacy journalist, or an opinion journalist.") Hannity has feuded with several conservatives who oppose Trump, including National Review's Jonah Goldberg, Wall Street Journal foreign affairs columnist Bret Stephens, and National Review editor Rich Lowry.  In 2017, Trump was reported to often call Hannity after his nightly Fox program.
