Why did congress pass the espionage act in 1917 and the sedition act in 1918?

Both were passed to keep people quiet 

The Espionage Act was passed to keep people from interfering with the military's attempt to defeat Germany, the point was to make it so that individuals could not publicly speak out or publish opinions on the topic. 

The Sedition Act was passed to keep people from speaking out about the president or the US government 

No we should just pass
