Hillary Clinton took a jab at President Donald Trump on Twitter just hours before his highly anticipated meeting with Russian President Vladimir Putin on Monday.

Trump is in Helsinki, Finland, for his first official meeting with Putin. Among other things, the two leaders are expected to talk about Russia’s meddling in the 2016 presidential election, Russia’s annexation of Crimea, and the war in Syria. But Trump has already admitted that he’s setting the bar low for the meeting and doesn’t expect major outcomes.

“I go in with low expectations,” Trump told CBS Evening News on Saturday. “I’m not going with high expectations.”

Despite this, it’s still a big deal that Trump is meeting with Putin. And Clinton is skeptical about Trump’s motives. On Sunday night, following France’s win in the 2018 World Cup, Clinton blasted Trump:

Great World Cup. Question for President Trump as he meets Putin: Do you know which team you play for? — Hillary Clinton (@HillaryClinton) July 16, 2018

And it seems like she had a good point: Just hours before the meeting was set to begin, Trump tweeted that the US is to blame for poor relations with Russia:

Our relationship with Russia has NEVER been worse thanks to many years of U.S. foolishness and stupidity and now, the Rigged Witch Hunt! — Donald J. Trump (@realDonaldTrump) July 16, 2018

The “Rigged Witch Hunt” refers to special counsel Robert Mueller’s probe investigating Russia’s interference in the 2016 presidential election. Just last week, Mueller indicted 12 Russian spies in connection with the hacking of the Democratic National Committee’s servers.

And although top Democrats called on Trump to cancel his meeting with Putin in light of Mueller’s stunning indictments, the meeting was not canceled and remains underway.
