In his remarks at a Pennsylvania campaign rally, Trump said that his wife is a "great first lady."

"Do you think the drug dealers that kill thousands of people during their lifetime, do you think they care who is on a blue ribbon committee? The only way to solve the drug problem is through toughness. When you catch a drug dealer, you've got to put him away for a long time."

Trump went on to praise the practice of executing drug dealers, and confirmed reports that he had spoken with Singaporean officials about the policy.
