06:13 AM EDT, 07/01/2025 (MT Newswires) -- AT&T ( T ) said it is "working diligently to better understand the issue" after US President Donald Trump publicly criticized the company's equipment during a conference call.

"I'm doing a major conference call with faith leaders from all over the country, and AT&T ( T ) is totally unable to make their equipment work properly," Trump wrote in a social media post Monday afternoon.

The company said its initial analysis indicated that the disruption was caused by "an issue with the conference call platform" instead of its network.

"Unfortunately, this caused the delay, and we are working diligently to better understand the issue so we can prevent disruptions in the future," AT&T ( T ) said in a social media post.
