Booth and Lincoln were not personally acquainted, but Lincoln had seen Booth at Ford's Theatre in 1863. After the assassination, actor Frank Mordaunt wrote that Lincoln, who apparently harbored no suspicions about Booth, admired the actor and had repeatedly but unsuccessfully invited him to visit the White House. Booth attended Lincoln's second inauguration on March 4, 1865, writing in his diary afterwards: "What an excellent chance I had, if I wished, to kill the President on Inauguration day!"
