Sen. Ron Johnson (R-Wisc.) tested positive for the coronavirus on Friday after returning to Washington, D.C., on Sept. 29 and coming into contact with someone who had contracted the virus, spokesperson Ben Voelkel said in a statement on Saturday.

Driving the news: Johnson is the third Senate Republican to test positive for the coronavirus, after news broke that President Trump tested positive early on Friday.

What they're saying: "Senator Johnson was exposed to someone who tested positive for COVID-19 on Sept. 14. He stayed in quarantine for 14 days without developing symptoms and tested negative twice during that time," Voelkel said, noting that Johnson then returned to D.C. and was exposed again shortly after Sept. 29.

  • "Senator Johnson feels healthy and is not experiencing symptoms. He will remain isolated until given the all-clear by his doctor. Most staff in senator's Washington office have been working remotely. The office will go all-virtual for the immediate future."

Super typhoon Surigae explodes to Cat. 5 intensity

Super Typhoon Surigae surged in intensity from a Category 1 storm on Friday to a beastly Category 5 monster on Saturday, with maximum sustained winds estimated at 190 mph with higher gusts.

Why it matters: This storm — known as Typhoon Bising in the Philippines — is just the latest of many tropical cyclones to undergo a process known as rapid intensification, a feat that studies show is becoming more common due to climate change.
