HAMBURG, Germany (AP) — The Latest on President Donald Trump's second official visit to Europe (all times local):

7:45 p.m.

The Russians have asked the U.S. for proof and evidence of their alleged interference in the 2016 election, which Russia denies.

Secretary of State Rex Tillerson says the ask was made during a lengthy meeting in Germany between President Donald Trump and Russian President Vladimir Putin.

Tillerson said the president pressed Putin on the issue and that they'd agreed to follow-up meetings.

That includes a new working group on cybersecurity and election interference.

Tillerson says, "the meeting was very constructive" and that the two leaders "connected very quickly."

For Vladimir Putin, a meeting Friday with President Donald Trump on the sidelines of the G-20 summit offers a long-sought opportunity to negotiate a rapprochement with Washington, but controversy remains over the Trump campaign’s ties to Russia. (July 6)

Secretary of State Rex Tillerson says that President Donald Trump and Russian President Vladimir Putin "had a pretty good exchange" as to how to handle the threat of North Korea.

But Tillerson added Friday after the leaders' meeting that the Russians "see it a little different than we do."

The top U.S. diplomat noted that Russia's ultimate goal mirrors what the United States wants: the denuclearization of the Korean peninsula.

He said the differences are the tactics used to achieve that goal. He did not elaborate.

Tillerson also said that, despite Trump's recent tweet to the contrary, the U.S. has not "given up hope" that China will help with North Korea.

Trump and Putin met for more than two hours at an international summit in Germany.

The statement says the leaders also discussed regional challenges, including drug trafficking, illegal migration, and the crisis in Venezuela. It does not say whether they discussed Trump's proposed U.S.-Mexican border wall.

A readout from the Mexican government said the two men underscored "the importance of modernizing" NAFTA in a way that "results in tangible benefits for the economies and societies of North America."

President Donald Trump's oldest son is complaining about the loud camera clicks that made it hard to hear his father and Russian president Vladimir Putin's brief remarks to the press ahead of their highly-anticipated meeting.

Donald Trump Jr. asks on Twitter: "With all the Cameras clicking away rapid fire you can't actually hear what they're saying? How many pictures do you need of the same scene?"

Professional news photographers typically take dozens or hundreds of shots of the same event to capture a variety of angles and facial expressions.

Trump and Putin are meeting at the Group of 20 world leaders' summit in Germany.

Reporters and photojournalists were allowed in the room for about two minutes to capture the scene.

Trump's son is a frequent critic of the press.

President Donald Trump appeared informal and relaxed; Russian President Vladimir Putin was steely.

The first face-to-face meeting between the two leaders was the spotlight of an international summit in Hamburg, Germany, Friday, amid tensions between the two countries over Russian involvement in the U.S. presidential election.

Trump said that his discussions with Putin are "going very well."

Speaking through a translator, Putin said they had spoken over the phone several times on "important bilateral and international issues," but that phone calls are "never enough." He said a face-to-face meeting is important to fostering "positive relations."

Trump says, "We look forward to a lot of very positive things happening for Russia and the United States."

After months of anticipation and intrigue, President Donald Trump and Russian President Vladimir Putin are sitting down for their first meeting.

The two exchanged brief pleasantries earlier Friday on the sideline of the G-20 summit of industrialized and developing nations.

Up front, Trump said he anticipates "a lot of positive things happening, for Russia, for the United States."

Their first sit-down meeting is expected to last for about 30 minutes and touch upon several complex issues, from the Syrian conflict to Russia's provocations in Ukraine.

However, the meeting also falls under the shadow of accusations that Russia meddled in the 2016 presidential election — and Trump is under pressure to raise those concerns with Putin in their first meeting.

Trump, on Thursday, said he believes Russia may have interfered in the election, but he said that he believes other countries may have been involved as well.

President Donald Trump was on the far left fringe at the Group of 20 summit — of the leaders' group photo, that is.

Trump's position as an outlier was merely a matter of protocol. Pride of place goes to the so-called G20 troika, consisting of current host German Chancellor Angela Merkel flanked by the host of the next meeting, Argentina's Mauricio Macri, and the host of the last one, China's Xi Jinping.

Trump wound up out on the wing between Indonesian President Joko Widodo and French President Emmanuel Macron. He has even less seniority than Trump does after being elected in May.

President Donald Trump is hailing Mexico's president as his "friend" in their first face-to-face meeting since Trump took office.

Trump maintains that he will build the border wall to keep drugs and criminals out of the U.S. — although those plans still remain unclear. He said Friday that he "absolutely" wants Mexico to pay for the wall.

Pena Nieto insists Mexico will not pay for the wall.

Trump said, "it's great to be with my friend the president of Mexico"

Pena Nieto said he hopes to continue a "flowing dialogue."
