Trump also later confirmed that he "does not believe in the validity of" many "votes cast, indicating that he lost the popular vote to Hillary Clinton in 2016.
"I say something that is controversial again, many voices have been cast that I do not believe," said Trump.
However, as part of the Trump campaign, poll numbers indicate concerns about its viability in some key states.
CNN and other outlets reported weeks earlier about the numbers that left Trump behind former vice president Joe Biden in states such as Michigan and Wisconsin. Later, however, a purge of the voting team was suggested Trump was angry at reporting on it.
At "Meet the Press", the President also spoke about the upcoming elections and confirmed that Vice-President Mike Pence would be his deputy for his passage in 2020.
But Trump was on the verge of offering pence confirmation for a hypothetical 2024 presidential election because the prospect is "so far away." Trump was asked the same hypothesis on "Fox and Friends" earlier this month.
"I do not even think about it, it's so far away, I mean, it's so far away, that's the only reason," Trump said to "Meet the Press," adding on Sunday. I do not know who will run or anything else. "
Trump also said it was" a tremendous embarrassment "for Biden, which former President Barack Obama did not the former vice president had still advocated.
He also said that he "could" address the interference of the elections in Russian President Vladimir Putin at the upcoming G20 summit.
"Will you tell him he should not do it?" Moderator of Meet the Press, Chuck Todd, asked.
Trump replied, "I can, if you want me to do it, I'll do that."
The President said he believes that Speaker of Parliament Nancy Pelosi is not giving in to the pressure within her caucus to initiate impeachment because she fears that this will benefit him politically.
"I think she feels that I will win much easier," said Trump. "I mean, that was said to me by many people."
Despite the argument that impeachment would improve his chances of re-election, the president said he disliked the ghost of impeachment hanging over him.
"That's not me. Look, I did not do anything wrong," Trump said, before calling the impeachment trial "a very unfair thing."
