Taylor Swift returns to the stage in London — a week after canceling her concerts in Vienna, Austria due to a terror threat.

Authorities foiled what they said was an ISIS-inspired plot to launch an attack at one of her concerts.

Three teenagers have been detained in connection with the plot and are suspected of planning a suicide attack.

Swift is scheduled to perform at London’s Wembley Stadium, which will take place amid heightened security.

Jason Russell, former U.S. secret service agent for former Presidents George W. Bush and Barack Obama, joined “The Rush Hour” on Thursday to discuss the concert security and the security failures surrounding the assassination attempt of former President Donald Trump.
