President Trump touted that his relationship with Russia President Vladimir Putin could help "solve" the North Korea "crisis" as well as dangers coming from other countries, a feat he says his his predecessor failed to accomplish.

"When will all the haters and fools out there realize that having a good relationship with Russia is a good thing, not a bad thing. There always playing politics - bad for our country. I want to solve North Korea, Syria, Ukraine, terrorism, and Russia can greatly help," Trump tweeted from Vietnam, Sunday morning local time, after saying that he had just had a successful meeting with Putin.

"Does the Fake News Media remember when Crooked Hillary Clinton, as Secretary of State, was begging Russia to be our friend with the misspelled reset button? Obama tried also, but he had zero chemistry with Putin," he later added, taking a swipe at his 2016 election challenger from the Democratic Party.

Trump met with Putin during the Asia-Pacific Economic Cooperation forum in Vietnam where the pair had "two or three short conversations, Trump told reporters on Air Force One on Saturday.

He said Putin denied Russia's election meddling in 2016 presidential election, claims which Trump indicated he believed were sincere, despite multiple contradictory reports from U.S. Intelligence agencies.

Critics, like Sen. John McCain, said Trump was choosing to side with Putin, a former KGB agent, over the U.S.'s own intelligence network.
