An investigation into Live Nation and its involvement in the deadly crowd surge that resulted in 10 fatalities and hundreds of injuries has been launched by a Congressional committee.

The House Oversight and Reform Committee sent a letter to Michael Rapino, president and CEO of Live Nation Entertainment, Inc., requesting information on what caused the November 5 event and how it was handled by the organizer.

"Recent news stories raise several issues about whether your firm did enough to guarantee the safety of the 50,000 concertgoers who attended Astroworld Festival, write committee leaders in a letter. We invite you to share your thoughts and concerns with us regarding what actions Live Nation and Ticketmaster took to prepare for the event, any warnings they received about possible hazards, and how they responded when people were injured or died as a result of the event."

Live Nation is required to respond by March 5. The Oversight Committee also sent a separate inquiry to Live Nation's main competitor in producing outdoor music events, AEG. The subcommittee chairmen are seeking answers on whether "adequate security" was provided at this year's event.

AEG owns Goldenvoice, which produced Coachella and Stagecoach music festivals. Live Nation has offered refunds to "everyone who purchased tickets" to the Houston-based event through its website. However, refunds will not be available for people who got tickets from a third party, such as a reseller or a scalper.

Live Nation refused to comment on the letters from Congress. The crowd surge on November 5 killed 10 people and injured hundreds more. Houston Police Department officials said at a news conference that they were investigating the incident as a homicide.

On January 21, the chief of the department announced that 10 lives were lost due to the incident. He also said an additional 169 people were hurt with non-life-threatening injuries.It was soon reported that eight people were arrested in the aftermath of the accident, but all 10 were set free.
