Thirty-nine-year-old Niviane Petit Phelps of Miami-Dade County has pled guilty in federal district court to a six-count indictment charging her with threatening to kill Vice President Kamala Harris.

During the change of plea hearing, Ms Phelps admitted that in February, she sent her husband, who was in prison, 30-second video clips of herself threatening to kill the vice president, said a statement by the U.S. Department of Justice.

The videos show Ms Phelps making the threats, screaming curse words, saying that she had accepted $53,000 to carry out the “hit” against Ms Harris, and explaining that she would assassinate the U.S. vice president within 50 days.

Some of the video clips she recorded herself; others she had her children record.

After sending these videos, Ms Phelps sent a photograph of herself holding a firearm with a target sheet at a gun range.

Two days later, Ms Phelps applied for a concealed weapon permit. She also admitted telling law enforcement officers who handled this case that she “doesn’t know” what would have happened if they had not come to her house.

Ms Phelps is scheduled for sentencing on November 19, at 2:00 p.m., before United States District Judge Jose E. Martinez, where she faces a possible maximum sentence of five years in prison
