After skipping all the Republican primary debates with the confidence of enjoying support from all over the country, former President Donald Trump said Tuesday he is ready for as many debates as necessary with the Democrat Joe Biden, believing that the incumbent President would not engage with him in such a discussion.

The 77-year-old told Fox News that he is ready it was "an obligation" for the candidates to engage in a debate.

Donald Trump — who is facing criminal indictments — skipped all the Republican presidential debates saying that he enjoyed massive support in the US.

His only competitor in the party is former US Ambassador to the UN Nikki Haley who has vowed to stay.

Trump said Tuesday: "Frankly, I think we have an obligation. When you have the final Republican, the final Democrat, you have the two people, you have to debate regardless of polls."

He added that he’d be willing to do "as many as necessary."

"I would like to do it starting now," Trump maintained during the interview adding "I don’t think [Biden’s] going to debate though. I really don’t think so."

The presidential debates are set to commence in September with three on the schedule.

The former commander-in-chief has easily secured victory in the first three primary contests starting from Iowa.

According to analysts, Trump’s decision to not participate in the Republican presidential debates could offer Joe Biden a justification to opt out of the election debates.

In December, the 81-year-old’s campaign official said that the president’s team “will have those conversations about debates in the future.”

Trump’s eagerness to engage in the debate with the president comes as poll results projected Trump with a narrow lead in a number of swing states, marking a shift in favour of the Republican candidate.
