WASHINGTON — This is an address from President Mike Bloomberg.

In his slickest commercial yet, the billionaire ex-Big Apple mayor and presidential wannabe has recorded a three-minute video “addressing the nation” on the coronavirus health crisis.

The taped clip is deliberately produced to look like a presidential address — the 78-year-old standing in front of an American flag in a room that is strikingly similar to the Oval Office.

The commercial named “Leadership in Crisis” will air on CBS and NBC at approximately 8.30 p.m. ET on Sunday night, his campaign said Saturday.

Bloomberg touts his leadership chops in times of crisis — capitalizing on allegations the Trump administration has bungled its handling of the heath outbreak.

“As the former mayor of New York City, I know it is critical that the federal government work in close partnership with state and local leaders who administer services and deploy first responders. That requires putting politics and partisanship aside,” he said in the address.

“I was first elected just weeks after the attack on 9/11 — a massive rebuilding, security and health challenge. In my 12 years in office, I dealt with a hurricane, a blackout, attempted terror attacks, the West Nile virus and swine flu.”

The head of Bloomberg News has poured at least $500 million of his vast $62 billion personal fortune into campaign ads.
