Cruz calls for Secret Service director's resignation
Sen. Ted Cruz, R-Texas, called for Secret Service Director Kimberly Cheatle to resign in a post on X on Monday.
Other Republican lawmakers have called on Cheatle to provide testimony, documents and explanations for the security posture that led to Saturday’s assassination attempt. Multiple committees have launched investigations and Cheatle has accepted an invitation to appear for a public hearing in the House next week.
Cruz’s social media post also called for Homeland Security Secretary Alejandro Mayorkas’ resignation, though this is not the first time that Cruz has called for Mayorkas to step down. He previously made similar calls over Mayorkas' management of the southern border.
