How could Michael send Fredo to Vegas if he has just committed a double murder and fled to Italy and was at this point not even acting Don?
If you pay attention to the scene in which Vito is broght up-to-date after being brought home from the hospital...it is Sonny who says that he's sending Fredo to Vegas.
Later when we see Michael visiting Vegas on business (to buy out Moe Green); Fredo has already been there for several years.

A wise and frugal government, which shall leave men free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned - this is the sum of good government.
