Trump starts big day in Germany with raging tweetstorm, claims 'everyone' there is talking about John Podesta and DNC hacks

President Donald Trump started his Friday with an early-morning tweetstorm from the G-20 summit in Hamburg, Germany.

Perhaps the tweet that garnered the most reaction was an attack on former Hillary Clinton campaign chairman John Podesta, who is apparently the talk of the G-20.

"Everyone here is talking about why John Podesta refused to give the DNC server to the FBI and the CIA. Disgraceful!," Trump tweeted.

It was unclear to what specifically Trump was referring. Podesta said recently that he had no idea whether the DNC had turned over its servers to the FBI - or whether intelligence agencies even asked for it.

Earlier in the morning, Trump kicked off the tweeting by offering thanks for the "great reviews" of his speech Thursday in Poland.

"My experience yesterday in Poland was a great one. Thank you to everyone, including the haters, for the great reviews of the speech!" Trump tweeted.

Business Insider's Natasha Bertrand was in Warsaw for the speech, and wrote, "At the Warsaw Uprising Monument in the city's Old Town, Trump was greeted by American flags, chants of 'USA! USA!' and banners reading 'Make Poland Great Again.'"

The president also recounted the meetings he has held with world leaders so far, and previewed a much anticipated sit down with Russian President Vladimir Putin.

"After Poland had a great meeting with Chancellor Merkel and then with PM Shinzō Abe of Japan & President Moon of South Korea," Trump tweeted.

"I look forward to all meetings today with world leaders, including my meeting with Vladimir Putin. Much to discuss," the president continued later.

Trump wrapped up his morning tweeting with a shot at a familiar target, the press.

"I will represent our country well and fight for its interests! Fake News Media will never cover me accurately but who cares! We will #MAGA!," Trump tweeted.
