It's fitting that President-elect Donald Trump attended an Ultimate Fighting Championship event last weekend. For his cabinet so far, he has tapped a pair of nominees ready to mix it up in grudge matches of their own.

Donald Trump is creating a show of force that will help define his new term as he tries to leverage Matt Gaetz into the attorney general’s office.

Now those who have tangled with Trump in the past are contemplating what they may be facing in the coming months if he follows through on his campaign rhetoric and uses the full force of the U.S. government to go after them.

President Joe Biden's apparent green light for Ukraine to strike Russia with US-made long-range missiles has caused consternation among Donald Trump's allies. Trump himself has not commented, but he won the election after promising to end the war - and people close to him have condemned the move as dangerous escalation.

The Kremlin said on Monday that Russia would respond to what it called a reckless decision by Joe Biden's administration to allow Ukraine to fire American missiles deep into Russia, which it said would draw the United States directly into the conflict.
