WASHINGTON, Oct 10 (Reuters) - Republican Senator Marsha

Blackburn wants the CEOs of AT&T ( T ), Verizon and

T-Mobile to disclose whether they received or objected

to subpoenas for phone data from eight U.S. senators that were

obtained by the Justice Department during a probe of the January

6, 2021, Capitol riot, according to letters seen by Reuters on

Friday.

On Monday, Senate Republicans disclosed a 2023 document that

showed the FBI obtained phone data known as "toll records" from

senators' phones, including Blackburn, which were tied to the

investigation of the riot.

She wants the telecom companies to answer a series of

questions including whether they provided "the cell phone

records of their personal devices, their official government

devices, or both?"
