He removed troops from Florida as stipulated in the Compromise of 1877.

Explanation:

Grant was the outgoing president in 1877. Following the hotly contested Election of 1876, officials had agreed to end Reconstruction if politicians from the South did not challenge Rutherford B. Hayes' election. Since Grant was the outgoing president, he removed troops from Florida as stipulated in the Compromise of 1877. Subsequently, Hayes eventually removed troops from South Carolina and Louisiana.
