You're kidding, right? Her testimony makes it clear that she did not support Trump's policies. And why didn't you guys care when Obama fired nearly all of Bush's appointed diplomats?
Are you kidding mike??
There are two types of Ambassadors - political appointees and career foreign service members. Both are presidential appointments but Obama only fired the former (as most presidents do).
The political appointees typically have no foreign service experience, they are appointed as part of the political game in DC. They could be a used car dealer who donated to the campaign or a high-school friend of the president or a political ally like a state representative or mayor. They typically have little or no diplomatic experience and usually they have a strong DCOM assigned under them to compensate for this lack of experience. These are almost always let go with a new administration, even with one from the same party. GHW Bush for example even fired many of Reagan's political appointees.
The second type are people who enlist in the foreign service and work their way up. They are professional diplomats and they are not typically let go with each new administration.
