Loyalty and leaks in the Trump administration

When a new president takes office there is a rush to replace the old staff with new people who are loyal to the new president. Trump having no experience on how government operates did not see this a priority. Many articles were written about the slow pace of replacing leadership not only in the White House but in other agencies. The result was that many left overs from the Obama administration stayed on the job much longer than the normal rate of replacement. These people found it necessary to shift their loyalties from Obama to Trump and many found this difficult and in some cases unpleasant. Some say this contributed to the extraordinary amount of leaking that occurred. Prime example the conversation between Trump and the PM of Australia conducted shortly after the election was published in the Washington Post and this type of thing became common place in Trumps first year and continues to some degree today.
