Joe Biden, 77-year-old presidential candidate, challenged 83-year-old voters to take push-ups or any physical exercise when he was criticized "too old".

Democratic presidential candidate Joe Biden on December 5 went to New Hampton, Iowa, to run for election and had a fierce response to an elderly voter when he questioned his health. like his son's relationship with Ukraine.

"I am not a Republican," the voter said. "I have two issues to discuss. First, the old man is almost the same as me. He is too old. I am 83 years old and I know very well that I am not as smart as before."

This voter then turned to the topic of Ukraine, especially the work that Hunter Biden, Joe Biden's son, had worked at Burisma gas company when his father was vice president of the United States. "He sent his son there to apply for a job at a gas company without any experience," the person asked.

When an assistant sought to remove the microphone from the elderly voter, Biden shook his head, asking the person to continue presenting his opinion, before he objected.

"The reason I participated in the election was because I had a lot of experience, had more knowledge than many people and could do a good job. If you want to test my fitness, take a push test, jogging or whatever you want, "Biden responded.

He also denied the Hunter-related allegations, insisting "no one said my son did anything wrong". The man below interrupted Biden, shouting that he "never said that Biden did anything wrong".

"He said that I arranged for my son to work at an oil company," the Democratic candidate said. "Is that what you just said? Be frank."

When the 83-year-old voter said he heard that information on MSNBC, Biden accused him of lying. "You didn't hear that information on MSNBC. You didn't hear it from anywhere. I won't argue here," the former US vice president said. In fact, Biden did not send Hunter to Ukraine to work.

When the 83-year-old voter continued to say no to Biden and said he was "not as determined as President Trump," the former vice president replied, "You are too old to vote for me."

Former US Vice President Joe Biden, who is leading the polls among the Democratic presidential candidates, is one of Trump's formidable opponents. The US president is embroiled in a impeachment investigation conducted by the US House of Representatives on allegations of pressure on his Ukrainian counterpart Zelenskiy, forcing Kiev to investigate Joe Biden and his father.

House Speaker Nancy Pelosi yesterday asked the House Judiciary Committee to draft Trump impeachment terms. After being passed by the lower house, accusations against the President will be submitted to the Senate for review. The US president will only be deposed if two-thirds of senators approve impeachment terms. This scenario is unlikely for Trump, because the US Senate is currently controlled by the Republican Party.
