New Jersey Gov. Phil Murphy urged people who attended President Trump's fundraiser in the state to get tested for the coronavirus after the president told Americans he had contracted the disease.

State health officials have already started the contact tracing process following Trump's afternoon gathering at his Bedminster golf club, said Murphy, a Democrat.

PRESIDENT TRUMP, FIRST LADY TEST POSITIVE FOR CORONAVIRUS, SET TO QUARANTINE AT WHITE HOUSE

"We urge everyone who attended yesterday’s event in Bedminster to take full precautions, including self-quarantining and getting tested," the governor said in a statement on Friday morning.

Trump tweeted earlier in the day that he and first lady Melania Trump had contracted COVID-19 and would be quarantining at the White House. His diagnosis, which came hours after long-time aide Hope Hicks fell ill with the virus, prompted the White House to cancel previously scheduled campaign events in Florida on Friday.

"We will get through this TOGETHER!" Trump wrote on Twitter.

“Tammy and I send our best wishes to President Trump and First Lady Melania Trump for a speedy and complete return to good health," Murphy said. “If there is one thing we have learned in New Jersey over these months, it’s that we pull together and support everyone fighting this virus."
