Acting U.S. Capitol Police chief Yogananda Pittman testified on Thursday that cellphone records show former USCP chief Steven Sund requested National Guard support from the House sergeant-at-arms as early as 12:58pm on Jan. 6, but he did not receive approval until over an hour later.

Why it matters: Sund and former House sergeant-at-arms Paul Irving clashed at a Senate hearing on Tuesday over a dispute in the timeline for when Capitol Police requested the National Guard during the Capitol insurrection.

• Irving insisted that he has no recollection of receiving the request until after 2pm. Lawmakers are looking for accountability over that hour of lost time, when pro-Trump rioters were able to breach and ransack the Capitol.
• "I did not get a request at 1:09 that I can remember," Irving, who resigned after the insurrection, testified. "The first conversation I had with chief Sund in that timeframe was 1:28, 1:30. In that conversation, he indicated that conditions were deteriorating and he might be looking for National Guard approval."

Details: Pittman testified to a House subcommittee that Sund's phone records show the former chief first reached out for National Guard support to Irving at 12:58pm.

• Sund then spoke to former Senate sergeant-at-arms Michael Stenger to make the same request at 1:05pm, per Pittman.
• Pittman says Sund repeated his request to Irving at 1:28pm, then spoke to him again at 1:34pm, 1:39pm and 1:45pm.
