Republican presidential candidate Chris Christie opened the second GOP primary debate by taking shots at former President Donald Trump. Minutes after the debate began on Wednesday, Christie was asked if Trump's populism was to blame for a possible government shutdown.

Republican presidential candidates Vivek Ramaswamy and Chris Christie will appear separately Tuesday during “Special Report,” Fox News’s nightly evening newscast, after being threatened with a ban from participating in future GOP debates if they appeared jointly on the network.

The Republican National Committee tipped the scales further in favor of Donald Trump winning the 2024 nomination by issuing a warning to two challengers about their upcoming scheduled appearances on Fox News.
