(The Hill) — President Donald Trump knocked AT&T after his conference call experienced glitches.

“I’m doing a major Conference Call with Faith Leaders from all over the Country, and AT&T is totally unable to make their equipment work properly,” Trump wrote Monday in a post on Truth Social.

“This is the second time it’s happened,” he continued. “If the Boss of AT&T, whoever that may be, could get involved It would be good. There are tens of thousands of people on the line!”

In another post, Trump apologized to the faith leaders for the “long wait,” adding that “AT&T ought to get its act together.”

“Please pass along the word to the tens of thousands of people who are there,” he continued. “We may have to reschedule the call, but we’ll use another carrier the next time. AT&T obviously doesn’t know what they’re doing!”

AT&T’s account on social platform X responded to screenshots of Trump’s post.

“We’ve reached out to the White House and are working to quickly understand and assess the situation,” the post read.

In a follow-up message, AT&T representatives said their initial assessment suggests the problem stemmed from the conference call platform, not from AT&T’s network.

“Unfortunately, this caused the delay, and we are working diligently to better understand the issue so we can prevent disruptions in the future,” according to the company’s statement.

A White House official confirmed to The Hill that AT&T reached out immediately but was unable to resolve the issue. A member of the White House team fixed the issue, according to the official, and the call started 20 minutes late.

The president updated approximately 8,000-10,000 faith leaders on his “many faith accomplishments” during the call, the official said.

The Hill has reached out to AT&T for comment.
