President Donald Trump has expressed displeasure with a coronavirus aid package and government funding legislation that Congress passed Monday, and he vetoed a $740.5 billion defense-policy bill Wednesday.

Meanwhile, U.K and EU officials announced a Brexit trade deal on Thursday after months of protracted negotiations and ending years of uncertainty around how a post-Brexit relationship between the two sides might take shape. The agreement now has to be ratified by U.K. and European parliaments.
