Hillary Clinton posted a tweet on Friday, making a subtle reference to President Trump.
Her tweet was short, simply reading, "Things I learned today," followed by a list of those things, "Russians Spy; Health care is complicated; Diplomacy is exhausting..."
The list was originally tweeted by Philippe Reines, a political consultant.

The heath care reference likely alludes to Trump's recent comment, "I have to tell you, it's an unbelievably complex subject...Nobody knew health care could be so complicated."
After Clinton posted her tweet, she received numerous supportive reactions. One Twitter user said, "2020 White House is yours if you want it! We'll fight for you always."
Another noted, "Our children will learn to throw shade with grace because of you."
Some pointed out the Russia issue, with one of those comments reading, "The Russian narrative is STRONG with the Trump administration. When will GOP wake up and choose America?"
