Former Transportation Secretary Pete Buttigieg has intensified criticism of the Trump administration, highlighting ethics concerns about Transportation Secretary Sean Duffy. The Atlantic report details financial and political activity involving Duffy, a former Republican congressman representing Wisconsin, which ethics experts argue violates the line between public office and political activities. Buttigigieg's comments came as the administration faced questions about governance and a series of high-level firings. The White House has defended Duffy as a key figure in advancing the administration's transportation agenda. This follows the dismissal of Attorney General Pam Bondi and Homeland Security Secretary Kristi Noem.
