Questions about U.S. President Joe Biden's health surfaced after he stumbled climbing up to the Air Force One on his trip to Atlanta. On Obamacare's 11th anniversary, Biden's breathing was audible between lines with his mask while delivering his speech.

Biden then asked Ohio State University officials if he was expected to keep his mask on.

"I guess I'm supposed to keep this on, correct?" Biden was quoted in a Breitbart News report, asking the University officials before he continued on his speech.

One of Biden's press secretaries earlier assured reporters that the Air Force One was just due to forceful winds.

This was not the first time that Biden's health raised eyebrows. In December, he accidentally referred to Vice President Kamala Harris as "President Harris" and called his wife Jill his sister, according to The Federalist report.

Obamacare Speech

Meanwhile, Biden announced in his speech the extension of the special enrollment for people to purchase Affordable Care Act health plans by three months, which would last until Aug. 15, according to an NBC News report.

The ACA, or usually known as Obamacare, will have a second extension that will help new and current enrollees avail of the enhanced subsidies in the COVID relief package that was signed earlier this month.

Biden mentioned in his speech his promise when he campaigned that he would build on the foundation of Obamacare, which is done by making health care more affordable.

"It means better coverage and lower premiums for millions of Americans," Biden was quoted in a report.

The additional subsidies brought by the COVID relief package will be available on Apr. 1 to people enrolling in coverage through HealthCare.gov.

Obamacare was considered a legislative achievement of former U.S. President Barack Obama, of whom Biden was the vice president during his administration.

Health Insurance Coverage in The U.S.

According to new data from the Census Bureau, 92 percent of the people in the U.S. had health insurance coverage in 2019.

This leaves eight percent or 26.1 million without any coverage throughout the year.

In 2019, adults ages 19 to 64-years-old had the highest uninsured rate at 11.1 percent, with children under 19 at 5.2 percent and adults 65 and older at 1.1 percent.

Race and ethnicity also play a part in factoring in health insurance coverage in the U.S. The Hispanic population had the highest uninsured rate, with 16.7 percent, throughout the whole of 2019.

For the Black population, 9.6 percent of the population were uninsured, while 6.2 percent for Asians. The white populations have the lowest uninsured rate with 5.2 percent.

According to a Pew Research Center survey in September, the majority or 63 percent of the U.S. adults said that the government has the responsibility to provide health care coverage for all.

This was a slight increase from last year's 59 percent. Meanwhile, 37 percent say that this is not the responsibility of the federal government.

The survey was done from Jul. 27 to Aug. 2 with 11,001 adult participants.
