He worked in radio and television since 1986 after he graduated from College of Mount Saint Vincent in the Riverdale section of the Bronx, New York.

On April 1, 2015, during the Imus in the Morning show on Fox Business, McGuirk called Apple CEO Tim Cook a "bigot hypocrite" for "running his mouth" about the subject of the religious freedom Indiana law passed the month prior.

First of all, Governor Cuomo tells all his state employees don't go to Indiana but he's going to Cuba where gay marriage is illegal and they maybe throw you in jail.

If he doesn't allow this Orthodox Jewish guy to refuse service...the point of the law is to allow him to exempt himself from a certain situation.McShane: This will end up back in the Supreme Court somewhere.McGuirk: And the governor of Connecticut.

If he really feels that way, stop marketing Apple products in Saudi Arabia, Iran, and Nigeria where they not only dump on women and treat them as second class citizens but as I said they would execute gay people.

For example, after the release of The Christian Science Monitor reporter Jill Carroll, who was kidnapped in Iraq, McGuirk stated: "She strikes me as the kind of woman who would wear one of those suicide vests.

Using a high-pitched Irish brogue ... the producer-as-cardinal said on the March 16 installment of the show that 'the only thing Hillary Clinton has in common with the late great President John Fitzgerald Kennedy, God rest his soul, is that they both enjoyed extramarital affairs with women.

[8] McGuirk played a role in an on-air incident on April 4, 2007, that caused a nationwide controversy and ultimately led to both him and Imus being fired.

During a discussion of the Rutgers University women's basketball team, Imus characterized the players as "rough girls with tattoos".

The ensuing "urban-speak" conversation involved Imus describing the girls as "nappy-headed hos" and McGuirk wondering if Imus meant to imply that the two teams looked like something out of Spike Lee's film School Daze, the "jigaboos versus the wannabes"; apparently referring to the two teams' differing appearances.

McGuirk was one of several people who rotated hosting of the post-Imus midday slot from May to October 2010 on WABC, a job that eventually went to Joe Crummey.

According to WABC personality Curtis Sliwa, McGuirk continued to work despite going through chemotherapy, and dealing with bouts of appendicitis and pneumonia.
