On the 9th (local time), one day before the announcement of the Nobel Peace Prize winner, U.S. President Donald Trump remarked on former President Barack Obama, a previous recipient of the award, saying, "He didn't do anything other than ruin our country, yet they (the Nobel Committee) gave him the award."

President Trump made the comments after a summit with Finnish President Alexander Stubb at the White House that day, when asked by reporters about the Nobel Peace Prize. "Obama received the award immediately after being elected (president)," he said.

President Trump added, "The worst president was 'Sleepy' Joe Biden, but Obama wasn't a good president either."

Former President Obama, who took office in January 2009, was named the Nobel Peace Prize laureate that October in recognition of his efforts toward nuclear non-proliferation and international diplomacy. President Trump has repeatedly expressed dissatisfaction, claiming that the former president received the award without any concrete achievements.

When asked about his own chances of winning the Nobel Peace Prize, President Trump claimed, "No one in history has solved eight wars in nine months," adding, "I have stopped eight wars."

Since the launch of his second administration in January, President Trump has publicly claimed to have ended seven armed conflicts, including those between Israel and Iran, and Pakistan and India.

Furthermore, by including the first phase of the Israel-Hamas Gaza peace initiative announced the previous day, he asserted that he has ended eight "wars."

Meanwhile, when asked about his health status, President Trump replied, "I am in very good physical health, and I am in very good mental health."

Following a medical check-up in April, President Trump is scheduled to undergo another examination on the 10th at the Walter Reed National Military Medical Center in Maryland, near Washington D.C.

He dismissed concerns raised in some quarters that the follow-up exam just six months later might indicate health issues.

President Trump said, "I had a check-up about six or seven months ago, and I always like to get checked early."

Regarding his cognitive test results from the April exam, he said, "I got a perfect score," adding, "Biden would have gotten the first three questions right. But Biden didn't get tested. Biden should have been tested."
