Answer:
Henry S. Johnston was impeached because people thought he had to much power
Step-by-step explanation:
As governor, Johnston successfully proposed the establishment of a crippled children's hospital and a large increase to school aid funds. His trouble began with complaints about his private secretary holding too much power and making executive decisions that he should be making. After an unsuccessful and unconstitutional special session to impeach the governor in 1927, a new group of state lawmakers impeached the governor in 1929.
