It comes after reports of significant service failures and delays on the Ticketmaster website that left fans unable to purchase tickets for the pop star's Eras Tour last Thursday.
Senator Amy Klobuchar said the incident had made the problem in ticketing markets"painfully obvious" as she and fellow Senator Mike Lee announced plans for the hearing. "Last week, the competition problem in ticketing markets was made painfully obvious when Ticketmaster's website failed hundreds of thousands of fans hoping to purchase concert tickets," Ms Klobuchar said.
"When there is no competition to incentivise better services and fair prices, we all suffer the consequences."Mr Lee added:"American consumers deserve the benefit of competition in every market, from grocery chains to concert venues.
