The situations aren't exactly apples-to-apples. Clinton was routinely dealing with sensitive information as secretary of state and actually set up a private server; Ivanka Trump's use seemed to involve transmitting her personal schedule and smaller-scale things.
But the whole episode adds to a laundry list of things the Trump White House has done that look a whole lot like the things it excoriated its predecessor (Barack Obama) and its 2016 opponent (Clinton) for.
Here are the big ones.
1) Emails and information security
What Trump said: "Hillary Clinton's attacks on you display the same sense of arrogance and entitlement that led her to violate federal law as Secretary of State, hide and delete her emails..."
"We can't hand over our government to someone whose deepest, darkest secrets may be in the hands of our enemies."
What he's done: Before Ivanka Trump, it was Kushner using private email in apparent violation of federal records laws. But that's not all. The President himself has reportedly shunned security concerns by continuing to use his personal cellphone. He has done this even as he has been told that China and Russia are monitoring the phone - exactly what he worried about when it came to such countries potentially hacking Clinton's server.
At the least, you'd think a guy who was so concerned about records laws and cybersecurity would take more care.
2) Foreign governments allegedly buying access
What Trump said: "Hillary Clinton ran the State Department like a personal hedge fund. It's hard to tell where the Clinton Foundation ends and where the State Department begins. Access and favours were sold for cash. It's called pay-for-play. Over and over and over, people who donated to the Clinton Foundation or who gave money to Bill Clinton got favourable treatment from Hillary Clinton's State Department."
What he's done: Another of Trump's favourite knocks on Clinton was the idea that foreign governments were buying access to and favours from the Clintons via donations to the Clinton Foundation. But since he's become president, foreign dignitaries and anxious would-be influencers have frequented Trump's Washington hotel - apparently in hopes of currying favour. The foreign clientele is at the centre of the emoluments lawsuit that has proceeded apace.
3) Intelligence briefings
What Trump said: "Fact - Obama does not read his intelligence briefings nor does he get briefed in person by the CIA or DOD. Too busy I guess!"
"Obama has missed 58% of his intelligence briefings. But our president does make 100% of his fundraisers."
What he's done: Trump's criticism was always overcooked. Obama didn't always get an in-person briefing, but he often read the president's daily briefing instead. Trump, though, doesn't even do that.
He has taken the briefing about once a week or less and often deputised Vice-President Pence to receive it. He reportedly doesn't read it. "I get it when I need it," Trump said. "I'm, like, a smart person. I don't have to be told the same thing in the same words every single day for the next eight years."
4) Divulging classified information
What Trump said: "We can't have someone in the Oval Office who doesn't understand the meaning of the word 'confidential' or 'classified.'"
"Like the Cold War, we also need to fight this battle by collecting intelligence and then protecting our classified secrets. Hillary Clinton has taught us all how much of a problem we have with cyber-security."
What he's done: In an Oval Office meeting last year with officials from America's Cold War opponents, Russia, Trump divulged highly classified information about a valuable stream of intelligence in the Middle East.
As president, Trump is able to declassify anything he wants, but the intelligence community fretted that the information would tip the Russians off to what the programme entailed and who was involved, which was a closely guarded secret.
5) Executive Orders to change the law
What Trump said: "Repubs must not allow Pres Obama to subvert the Constitution of the US for his own benefit & because he is unable to negotiate w/ Congress."
"My contract calls for the appointment of judges who will uphold and defend the Constitution of the United States. Hillary wants to go even further than Obama on illegal executive action. I will terminate every single illegal Obama executive order and will restore the constitutional rule of law."
What he's done: Trump has used Executive Orders 86 times in the first two years of his presidency, compared to Obama's 276 and George W. Bush's 291 both over eight years. At this rate, Trump is on track for at least 344 over eight years, should he be re-elected.
