與此同時，美國的報道稱美國司法部正在調查Ticketmaster的母公司Live Nation Entertainment。紐約時報》周五的報道稱，該調查早於本周的混亂局面。
Ticketmaster已經受到了政府的監督，這種監督是在2010年與Live Nation合併時實施的--Live Nation經營着美國的許多活動場所並擁有藝術家管理業務。幾年前，在監管機構發現該公司違反了協議條款後，這種監督被延長。
"We asked them, multiple times, if they could handle this kind of demand and we were assured they could," she wrote, in her first public statement addressing the fiasco.
In the statement on Instagram, Swift wrote: "Over the years, I've brought so many elements of my career in house. I've done this SPECIFICALLY to improve the quality of my fans' experience by doing it myself with my team who care as much about my fans as I do.
"It's really difficult for me to trust an outside entity with these relationships and loyalties, and excruciating for me to just watch mistakes happen with no recourse."
Swift said it was "truly amazing that 2.4 million people got tickets" but annoyed her that "a lot of them feel like they went through several bear attacks to get them". Many fans in the presale complained the website crashed repeatedly after waiting hours in the queue.
The problems have refocused the debate in the US on Ticketmaster's dominance, which has long faced complaints that it abuses its power over the industry, with US Democratic Senator Amy Klobuchar announcing there will be a Congressional hearing to investigate the website.
Meanwhile, reports in the US claim the US Department of Justice is investigating Ticketmaster's parent company, Live Nation Entertainment. The report in The New York Times on Friday said the inquiry predates this week's chaos.
And last month, US President Joe Biden - who has expressed concern that monopolies have become more common across the economy - said his administration would look into fees on concert tickets.
Ticketmaster is already subject to government monitoring, oversight that was imposed when a 2010 merger with Live Nation - which runs many of the country's event venues and has an artist management business - was approved. The oversight was extended a few years ago after regulators found the firm had violated the terms of the agreement.
Following the chaos this week, Ticketmaster said: "While it's impossible for everyone to get tickets to these shows, we know we can do more to improve the experience and that's what we're focused on."
