NEW You can now listen to Fox News articles! Transportation Secretary Sean Duffy and his wife, "Fox & Friends" co-host Rachel Campos-Duffy, fired back on Friday after former Sec. Pete Buttigieg and his husband launched a barrage of attacks against the Duffys' upcoming "Great American Road Trip" reality TV series. The feud ignited Friday after the couple announced the new show on "Fox & Friends." Chasten Glezman Buttigieg quickly took to X to bash the project, accusing the Duffys of taking a "multi-month, taxpayer-funded family road trip" while gas and grocery prices soar due to "Trump's war of choice." He went on to call the couple "unfocused, unserious, and out of touch," and aired old grievances about the Duffys' past criticism of Pete Buttigieg working from his son's ICU bedside.
