According to former US President Donald Trump, the most challenging country to deal with is not Russia or China but is in fact the United States itself.

In his first rally this year in Arizona on Saturday, Trump expressed that he is often asked which country is most challenging to engage with, potentially China, Russia, or Iran. Trump said in fact, none of those countries are more difficult to deal with than the United States.

Trump expressed that "we have some crazy people, where they create Russia, Russia hoax, and all created, all fabricated."

According to the former President, the US has "lost its greatness as a country," which is not a surprising statement from a President whose campaign was centered around "Making America Great Again."

He claimed that Democrats are being overtaken by left-wing fascism and accused them of obstructing the 2020 presidential results. Trump pledged he would return as President in 2024, which some are calling a "soft-launch" for his campaign.

"After four years of Russia, Russia, Russia; Ukraine, Ukraine, Ukraine, the impeachment hoax number one, the impeachment hoax number two, …and the harassment of my family … now the radical Democrats have yet another witch hunt no different than Russia, Russia, Russia: the Unselect Committee of political hacks [investigating the January 6 events]," Trump said, referring to the probe into the January 6 Capitol attack.

Trump has been repeatedly accused of inciting the violent storming of the US Capitol on January 6 of last year.

Earlier, the former US President Donald Trump's appeal to keep records related to the January 6 capitol storming hidden was denied.

The House select committee investigating the Capitol attack closed in on Donald Trump’s inner circle, issuing subpoenas to three new White House officials involved in planning the former President’s appearance at the rally that preceded the 6 January insurrection.

Several hundred rioters claiming the vote was rigged stormed the Capitol on January 6, as Congress was about to officially certify Biden's victory in the US presidential elections.

The violent and chaotic attack resulted in the death of five people at the Capitol, including a policeman. Trump has refused to admit defeat to Biden and continues to make baseless claims that he won the election.
