“In light of dangerous NKorea threat, I'm stopping all petty political disagreements for at least next 12 hours. Let's see what others do,” he tweeted at about 3 p.m.

But just after 11 p.m., moments after his Fox News show ended, Hannity attacked McConnell in response to a report on him blasting President Trump’s “excessive exceptions” on passing legislation.

“@SenateMajLdr No Senator, YOU are a WEAK, SPINELESS leader who does not keep his word and you need to Retire!” he tweeted.

Hannity has been a strong supporter of Trump and defends him regularly, often criticizing McConnell and other Republican leaders for not supporting Trump enough.

The Fox host has ripped McConnell over the Senate GOP failing to pass an ObamaCare repeal-and-replace bill late last month when three Republicans voted against it.

News emerged Tuesday that North Korea, which has been threatening nuclear war with the U.S., has successfully tested two ballistic missiles that officials say could reach the U.S.
