Could the Environmental Protection Agency be an extinct species soon

President Trump has already shaken up activities at the EPA.  No social media post by employees.  Media not allowed near the agency.  Could this be the first agency to go in a Trump administration. Most Americans believe this an intrusive agency needs to go away.  No more global warming projects and projects that prevent the American economy.  Only the House and Senate can actually shut down an agency.  The executive branch can weaken an agency.
