For over a year, Donald Trump has been forced to push back against reports that his presidential campaign had been in cahoots with Russia. In his latest series of tweets, Trump attempted to throw cold water on those claims by publicly calling out the Kremlin.

Trump on Russia

Following his shocking upset win over Hillary Clinton in November 2016, it was only a few weeks later when several well-respected news outlets and government agencies came to the conclusion that Russia hacked into the election with the goal of electing Donald Trump.

Since then, an offical investigation has been set up to look deeper into the claims, led by former FBI director turned special counsel Robert Mueller. As expected, Trump and his team have denied any wrongdoing, often repeating their defense of "no collusion," while referring to the reports as "fake news."

While Donald Trump normally refuses to criticize Russia and President Vladimir Putin, over the last week his message has changed.

Following a chemical attack in Syria carried out by the Assad regime, which is backed by Putin, Trump has decided to hit back with tweets on April 11. "Russia vows to shoot down any and all missiles fired at Syria. Get ready Russia, because they will be coming, nice and new and 'smart!,'" Trump tweeted. The commander in chief then warned Russian not to be allies with a "Gas Killing Animal" like Assad.

In a follow-up tweet, Donald Trump doubled down on his attack.

"Our relationship with Russia is worse now than it has ever been, and that includes the Cold War," Trump tweeted, before suggesting that the Kremlin "stop the arms race" so that the two countries could work together.

In a third tweet, Donald Trump elaborated on the current Robert Mueller investigation into Russian meddling,calling it "Fake and Corrupt" and a political attack led by "Democrat loyalists, or people that worked for Obama," Trump tweeted. "Mueller is most conflicted of all," the president added, before repeating that there is "no collusion."

Twitter reacts

After Donald Trump's threat to Russia, critics of the president decided to chime in. "Can someone put him in a diaper and spank him until he calms down?" one tweet read.

"The president of one of the worlds greatest superpowers trolling threats at another world leader on Twitter .... seriously, wtf?? I feel sorry for the USA. We may be tiny, but at least we have some dignity," a Twitter user wrote.

"Why is 'smart' in quotation marks?" a tweet wondered.

"What happened to your complaints about a president tipping the enemy off to our military moves before we make them? This is twice this month you’ve done that," a social media user wrote. "Says the orange buffoon who wants to strip health care away from millions of people. It’s just a slower mass murder. A**," a follow-up tweet went on to read.
