The Trump hotel chain is dealing with an attack on its computer systems for the second time in 6 months, according to CNN.
The Trump Hotel Collection acknowledged on Monday that it was attacked. The incident is being investigated by the FBI and CIA.
Trump's son, Eric Trump, says that they are routinely targeted by cyber terrorists and that the company is committed to safeguarding its guests' personal information.
The hackers reportedly placed malicious software on the hotel chain's payment system. Anyone who visited a Trump hotel between May 19, 2014 and June 2, 2015 may have been affected. Especially if they visited hotels in Chicago, Honolulu, Las Vegas, Miami, New York and Toronto.
