President Donald Trump and Rep. Alexandria Ocasio-Cortez were involved in a Twitter spat after Trump tweeted numerous times within an hour lashing out at "Do Nothing Democrats" and the media.

In his tweet, Trump branded Cortez a "wack job." She responded to his tweet with one of her own, saying it was better being a wack job than some "criminal who betrays our country."

The Twitter spat came even as Trump’s rolled out a defense strategy against the Democracts' impeachment inquiry against him -- of trying to normalize his efforts at soliciting other countries' governments to investigate his political opponents.

On Thursday, Trump had publicly called on China to investigate Joe Biden and his son, Hunter Biden, an action which, according to the Democrats, amounts to an offense that could lead to impeachment. 

Trump justified his actions, even after the Federal Election Commission deemed that asking for help from foreign nations would be considered illegal, saying that it was about “corruption on a massive scale” and not the re-election campaign.

He claimed that it was his right as the President of the United States to investigate corruption and that there was nothing wrong with asking or suggesting other countries to help.

“As the President of the United States, I have an absolute right, perhaps even a duty, to investigate, or have investigated, CORRUPTION, and that would include asking, or suggesting, other Countries to help us out!” Trump tweeted.

Trump and his personal lawyer Rudy Giuliani have accused Joe Biden of improperly helping his son’s business ventures in foreign countries. The President has also hit out at Democrats for allegedly spreading fake news and accused them of engineering a coup against him

In his barrage of tweets, Trump also threatened to sue Speaker Nancy Pelosi for saying Adam Schiff didn’t fabricate his words in front of the Congress. 

“Nancy Pelosi today, on @GMA, actually said that Adam Schiffty Schiff didn’t fabricate my words in a major speech before Congress. She either had no idea what she was saying, in other words lost it, or she lied. Even Clinton lover @GStephanopoulos strongly called her out. Sue her?” Trump tweeted.

This half impulsive, half-wild strategy of constantly downplaying the impeachment investigation might reap benefits for Trump. The President has largely remained firm in justifying his actions and trying to pass the blame on to his political rivals.  

If he is able to retain the Republican voters in his corner by taking control of the narrative and being in charge, the elected representatives in the Senate, who have the final say, would find it hard to abandon him when a case would be eventually presented, reports said. 

"I think Biden is going down. And I think his whole situation — because now you may very well find that there are many other countries that they scammed, just like they scammed China and Ukraine. And basically, who are they really scamming? The U.S.A. And it's not good," Trump further said.

Trump is trying to convince the voters that he is on their side and has nothing to hide, but political analysts say the gamble could backfire, as the President is only confirming the allegations against him.
