"We have been very strong on Russia", Trump told reporters at the British premier's Chequers country residence, after talks with May.
Lawmakers on both sides of the aisle on Friday called on President Donald Trump to consider canceling his summit with Russian President Vladimir Putin set for next week in Finland following a new indictment in the Russia investigation.
"If he does do this meeting he should do nothing less than hand Putin these indictments and the previous indictments and demand immediate extradition of all the individuals", Mr. Perez said.
Sen. Elizabeth Warren (D-Mass.) tweeted tersely to Trump to "cancel your ridiculous Putin summit and get your butt on a plane back to the United States".
The indictment lays out a sweeping effort starting in March 2016 to break into key Democratic email accounts, such as those belonging to the Democratic National Committee, the Clinton campaign and the Democratic Congressional Campaign Committee.
"Cancel the Putin meeting. He needs to tell Putin, "don't mess around anymore because we are the 800-pound gorilla", he said during an interview with FOX Business" Liz Claman on Friday.
"I will absolutely bring that up". "I think you will probably be rewarded mightily by our press".
Latest as Trump due to arrive in UK
Here is what 20 people who we spoke to on the streets of London thought about the U.S. president's upcoming visit. The US president has angered many in Britain in the last two years with a series of actions and pronouncements.
Foreign Secretary Jeremy Hunt has said Donald Trump is right to demand other North Atlantic Treaty Organisation allies contribute more to the costs of their collective defence. I don't think. But you never know what happens.
Rep. Ted Lieu (D-Calif.) also called for the cancellation of the meeting, saying that Trump "cannot claim to love the USA while meeting with. a man who is overseeing an all-out attack on America's democracy".
But less than three hours later, the California Democrat joined the chorus of party members calling for the meeting to be canceled. Bernie Sanders (I-Vt.) argued that Trump should use the planned meeting to confront Putin over the new charges and pressure him on his alleged role in election meddling.
Rep. Debbie Wasserman Schultz of Florida, who was Democratic National Committee chairwoman at the time of the hacking, issued a statement Friday that said the organization "was the first major target of the Russian attack on our democracy".
"It is obvious to me that President [Trump] attaches a great deal of importance to this". The White House didn't respond to a request for further comment on whether Trump would address the indictment when he meets with Putin.
Spokeswoman Lindsay Walters adds in her statement that "this is consistent with what we have been saying all along".
The 29-page indictment did not allege that Trump campaign associates were involved or that any Americans were knowingly in contact with the Russians.
