Former Secretary of State Hillary Clinton famously used a private email account for Government email (the first image is from Hillary's discussion of her private email account in March 2015).
Ivanka Trump, daughter of current President Trump and advisor to the President (seen in the second image) also used a private email account for Government email.
Donald Trump, both as a candidate for President and as President criticized Hillary and defended Ivanka.
Is this hypocrisy?
First off, it is legal to use private email for government business and in some situations necessary (I did this myself when the government server was down). However, such use has restrictions, for example, if you send government email using a private account, you are supposed to send a copy to your government email account to comply with the government records regulations. Also, you may not use private email to hide your actions or send government information to unauthorized persons and, most importantly, you may not use private email to send classified information (in fact you may not use regular government email for classified purposes, you must use the classified network).
As far as I can tell, Ivanka is guilty of using private email when there was no need to do so and also for sending government information to non government officials.
Hillary, on the other hand, was guilty of just about everything you could think of, including destruction of her emails and privately constructed server which held government records not elsewhere available and transmitting confidential (even secret) information on a non government email account. So the two situations are not equivalent and criticizing Hillary while, in part defending Ivanka is certainly reasonable, although Ivanka does bear a certain measure of guilt.
Both President Donald Trump and former President Barack Obama played golf during their time as President.
The first image is of Trump in Scotland (I think at Saint Andrews, although the Trump Organization licenses a course with the name Andrews in Ireland) in July 2018 (Getty image) subsequent to a State visit.
The second image is of Obama in 2011 with former Speaker of the House John Boehner. They are playing golf one of the three golf courses on the grounds of Andrews Air Force Base.
Both Trump and Obama were arguably mixing recreation with Presidential business.
The only difference here is that during his campaign for President, Trump criticized Obama's devotion to golf as a example of not working. CNN put together a number of clips of this and it is available here.
Whether this is hypocrisy or Trump changing his mind or just performance art is difficult to determine. I'm inclined to think Trump just doesn't care about being consistent and although it is hypocrisy, it is a casual, not strategic kind of hypocrisy.
In any event, one thing Obama and Trump have in common, in my opinion, is a reluctance to develop their own legislative language. Obama, for example, famously relied on Congress (primarily through then Senator Baucus) , on the legislation that came to be known as Obamacare. Trump, relied a collection of House Republicans for his signature Tax restructuring bill. Surely golf must be more fun than reading through proposed statutes.
In mid 2017, US Senator Elizabeth Warren was one of the leaders of a call for Attorney General William Sessions to resign.
Now, less than 18 months later she is calling the resignation of Sessions a constitutional crisis.
It could be that Warren changed her overall opinion but allows to the opinion that Sessions has 'protected' the work of special prosecutor Mueller.
However, I can't find any evidence prior to November 2018, of, say, a Warren statement praising Sessions or a Warren statement saying she was wrong in calling for Sessions to resign.
If these don't exist, then it would be hypocrisy.
