There has been a barrage of criticism in the US after President Donald Trump defended Russia over claims of interference in the 2016 elections.
At a summit with Russian President Vladimir Putin in Finland, Mr Trump contradicted US intelligence agencies, saying Russia had no reason to meddle.
The top Republican in Congress, House Speaker Paul Ryan, said Mr Trump must see that “Russia is not our ally”.
Republican Senator John McCain said it was a “disgraceful performance”.
Mr Putin denied the interference claim.
The US and Russian presidents held nearly two hours of closed-door talks in the Finnish capital Helsinki on Monday.
What did President Trump say?
At a news conference after the summit, he was asked if he believed his own intelligence agencies or the Russian president when it came to allegations of meddling in the election.
“President Putin says it’s not Russia. I don’t see any reason why it would be,” he replied.
Mr Trump also blamed poor relations with Russia on past US administrations rather than Russian actions.
US intelligence agencies concluded in 2016 that Russia was behind an effort to tip the scale of the US election against Hillary Clinton, with a state-authorised campaign of cyber attacks and fake news stories planted on social media.
Mr Trump later backtracked, tweeting that he had “great confidence in my intelligence people”.

As I said today and many times before, “I have GREAT confidence in MY intelligence people.” However, I also recognize that in order to build a brighter future, we cannot exclusively focus on the past – as the world’s two largest nuclear powers, we must get along! #HELSINKI2018
What has US reaction been?
In a strongly-worded statement, Mr Ryan said: “There is no moral equivalence between the United States and Russia, which remains hostile to our most basic values and ideals.
He added that there was “no question” Moscow had interfered in the 2016 election.
Sen McCain, a key member of the Senate Armed Services Committee, said it was a “disgraceful performance” by a US president.
“No prior president has ever abased himself more abjectly before a tyrant,” Mr McCain said in a statement.
Another senior Republican, Sen Lindsey Graham, also a member of the Senate Armed Services Committee, tweeted that it was a “missed opportunity… to firmly hold Russia accountable for 2016 meddling”.
In a series of tweets, Senate Democratic leader Chuck Schumer said Mr Trump’s actions had “strengthened our adversaries while weakening our defences and those of our allies”.
The US Director of National Intelligence, Dan Coats, also issued a statement saying that the intelligence community had been clear about Russia’s “ongoing, pervasive attempts” to undermine US democracy.
Former CIA director John Brennan said Mr Trump’s news conference “was nothing short of treasonous”.
“Not only were Trump’s comments imbecilic, he is wholly in the pocket of Putin. Republican Patriots: Where are you???” he tweeted.
Meanwhile, Vice-President Mike Pence, in a speech at the US Department of Commerce, defended the summit and praised President Trump.
