Chelsea Clinton responds to Donald Trump's G20 tweet in the best way possible.

U.S. President Donald Trump responded on Monday to criticism over his daughter taking his seat at the G20 world leaders summit in the only way he knows how—by calling out a Clinton.

It didn’t end well.

The latest dust-up started when a photo showing first daughter Ivanka Trump at the G20 table in Germany went viral, leading people to wonder how the 35-year-old businesswoman woman, former model, and current White House employee was qualified to have a seat alongside the world’s leaders.

Today, President Trump offered an explanation:

“When I left Conference Room for short meetings with Japan and other countries, I asked Ivanka to hold seat. Very Standard.” President Trump tweeted earlier this morning.

When I left Conference Room for short meetings with Japan and other countries, I asked Ivanka to hold seat. Very standard. Angela M agrees!

He should have stopped there.

After all, he is correct, said German leader Angela Merkel: “The delegations themselves decide, should the president not be present for a meeting, who will then take over and sit in the chair,” Merkel told reporters in defence of Ivanka on Sunday.

Problem is, Trump didn’t stop there. Instead, he doubled down with a second tweet, this time referencing former first daughter Chelsea Clinton.

(Note to Trump: Calling out Chelsea Clinton is never going to end well for you.)

If Chelsea Clinton were asked to hold the seat for her mother,as her mother gave our country away, the Fake News would say CHELSEA FOR PRES!

A quick reminder: Chelsea’s father is former U.S. President Bill Clinton. Her mother is Hillary Clinton, former U.S. Secretary of State and 2016 Democratic candidate for President.

Chelsea has earned numerous graduate degrees, including a doctorate in international relations from Oxford University. Even so, she never “sat in” at a G20 summit meeting for her parents.

Chelsea fired straight back.

Good morning Mr. President. It would never have occurred to my mother or my father to ask me. Were you giving our country away? Hoping not. https://t.co/4ODjWZUp0c

“It would never have occurred to my mother or my father to ask me,” she tweeted. “Were you giving our country away? Hoping not.”

Thankfully, there is one nugget of logic to come out of this exchange:

#ChelseaForPres, anyone?
