House Oversight Committee issues subpoena for Secret Service director's testimony

The House Oversight Committee on Wednesday issued a subpoena for the Secret Service director to testify next week on the attempted assassination of Donald Trump. 

The committee had written to agency Director Kimberly Cheatle on Tuesday to request a voluntary hearing July 22, which the Secret Service originally said she would attend. However, after Department of Homeland Security officials intervened in scheduling, the director's attendance was called into question, House Oversight Chairman James Comer said in a letter released alongside the subpoena.
