What does this mean?

Question

"It is apparent to my mind that the President thoroughly believed the tenure of office act to be unconstitutional and void . He was advised by every member of his cabinet......
"This was a punitive statue. it was directed against the President alone. It interfered with the prerogatives of his department as recognized from the foundation of the Government... This government can only be preserved and the people maintained by preserving intact the co-ordinate branches of it -legislative, executive, judicial - alike. I am no convert to any doctoring of the omnipotence of Congress." Okay so I understand about the first paragraph but not the second. Please help me.

Answer 1

The speaker believed that congress had no power to prevent him from firing office holders. He believed the office holders worked for him, not congress.
