Hundreds of people were at Liberty State Park Saturday participating in the Earth Day 5K, including Gov. Phil Murphy.
The run comes just one day after the governor called for the Mississippi state flag to be removed from the park.
The Mississippi state flag contains the Confederate flag emblem and Gov. Murphy says that is not what New Jersey stands for.
"New Jersey's strength is rooted in our diverse communities," Murphy said in a statement. "The Confederate symbol displayed on the Mississippi state flag is reprehensible and does not reflect our values of inclusivity and equality."
The emblem has been on the Mississippi state flag since 1894.
