BOSTON — U.S. Rep. Joe Kennedy III is set to announce a Democratic primary challenge to U.S. Sen. Edward Markey of Massachusetts in 2020.

A person with knowledge of Kennedy’s plans told The Associated Press he will formally make the announcement Saturday. The person wasn’t authorized to pre-empt Kennedy’s announcement and spoke Wednesday on condition of anonymity.

The 38-year-old grandson of Robert Kennedy has been weighing a decision for several weeks.

The 73-year-old Markey has said he plans to run for reelection no matter who else gets in the race.
