Voters in northern Kentucky on Tuesday rejected the incumbent congressman Thomas Massie, who has been critical of Donald Trump, in favor of the president’s hand-picked candidate.

Ed Gallrein, a retired navy Seal and farmer who was recruited into the race by Trump, defeated the seven-term incumbent in a primary election in Kentucky’s fourth congressional district in what the president’s allies framed as a win for Maga’s hold over the Republican party.

Where else held primaries on Tuesday?

Pennsylvania, Georgia, Alabama, Oregon and Idaho. Georgia also delivered a defeat to a prominent Trump critic, while a Trump ally won in Alabama, too.

How significant was Kentucky?

Massie, a seven-term incumbent, has been an outspoken GOP opponent to Trump – repeatedly clashing with the president over Iran, government spending and the Jeffrey Epstein files. In response, Trump treated the primary as a personal vendetta.

The pair held talks in the Great Hall of the People on Wednesday morning, as Xi did with Trump last week, when the leaders discussed issues including trade, the Iran war and Taiwan.

What is at the top of the agenda?

For Putin, it is likely to be reciprocal trade and investment, as Russia’s economy continues to suffer over the cost of its war in Ukraine and related sanctions. China, Russia’s largest trading partner, buys almost half of Moscow’s oil exports.

What about foreign policy?

Xi said the world was in danger of returning to the “law of the jungle”, adding that further hostilities in the Middle East were “inadvisable”, and calling for a ceasefire, state media reported.

US Senate votes to advance resolution to curb Trump’s Iran war powers Senator Bill Cassidy of Louisiana voted with the Democrats, joining Republicans Lisa Murkowski of Alaska, Rand Paul of Kentucky and Susan Collins of Maine in doing so.

Photograph: Kylie Cooper/Reuters The Senate voted on Tuesday to advance a war powers resolution aimed at forcing Donald Trump to end the war in Iran unless he receives congressional authorization to continue it.

Tuesday’s 50-47 vote marks the first time the chamber has advanced the bill, the eighth attempt at doing so since the conflict began in February.

The Senate’s vote marks just the first step toward full passage of the resolution, which Trump will almost certainly veto even if advances through both the Senate and the House.

How did the vote pass this time?

Four Republicans crossed the floor to join all but one of the Senate’s Democrats in voting to pass the bill. Senator Bill Cassidy, of Louisiana, joined Lisa Murkowski of Alaska, Rand Paul of Kentucky and Susan Collins of Maine in voting for the bill. The latter three did so in previous votes too. Pennsylvania’s John Fetterman was the sole Democrat to vote against it.

If Trump vetoes it, what is the point?

Democrats see it as a way to force Republicans to take a stance on Trump’s unpopular war.
