Biden acknowledges nation's COVID-19 testing shortages: report

Special: Battle Against Novel Coronavirus

U.S. President Joe Biden acknowledged the shortage in domestic coronavirus testing facilities, the U.S. News and World Report has reported.

"It's not enough. It's clearly not enough," Biden was quoted as saying on Monday. "If we had known, we would have gone harder, quicker if we could have."

Holiday travel, paired with the rapid spread of the Omicron variant, led to a high demand for tests and empty shelves at stores that sell at-home tests, said the report.

However, testing issues are not a new problem for the country, as many experts decried shortages during the surge of the Delta variant, it added.
