The motorman allegedly made the comments Wednesday morning as several officers from the Special Operations Division discussed threats against President Obama. It was not immediately clear where the alleged conversation took place or exactly how many officers took part in the conversation.

During that conversation, the officials said, the officer allegedly said he would shoot the First Lady and then used his phone to retrieve a picture of the firearm he said he would use. It was not immediately clear what type of firearm was allegedly shown.

Secret Service spokesman Ed Donovan told ABC Radio, "We're aware of the situation and taking the appropriate steps."
