Trump calls off Putin meeting over Ukraine crisis

Trump tweeted en route to the summit.

"Based on the fact that the ships and sailors have not been returned to Ukraine from Russian Federation, I have decided it would be best for all parties concerned to cancel my previously scheduled meeting", he wrote. Trump has denied any wrongdoing and on Thursday called Cohen a "weak person" looking for a reduced sentence.

Both Trump and Putin were in the same room for the "family photo" - the time when all the G20 leaders gather on stage for a group picture.

Trump on Tuesday threatened to cancel the meeting due to his displeasure with Russia's alleged "aggression" of Ukraine near the Kerch Strait that separates the Black Sea and the Sea of Azov.

Commenting on the move, the White House said Trump made the decision on the way to Buenos Aires after discussing the Kerch strait incident with US Secretary of State Mike Pompeo, Chief of Staff John Kelly and National Security Adviser John Bolton.

Trump appears to have chose to follow through on that threat - a decision that marks one of the strongest signals yet he's willing to hold Russian Federation to account for its belligerence in the region.

Ukraine's President Petro Poroshenko says his intelligence services believe Russian Federation is planning an invasion of his nation, and called for assistance from North Atlantic Treaty Organisation.

After warning of the threat of "full-scale war", Ukrainian President Petro Poroshenko on Wednesday signed an act imposing martial law for 30 days in regions bordering Russian Federation, the Black Sea and the Sea of Azov.

A massive security operation is under way for the summit in Buenos Aires. She was expected to arrive late to the summit, and the meeting did not appear on Trump's schedule for Friday.

Evidently the White House realized on Thursday that the optics of a Putin meeting, coming at a time when Trump was already accused of being soft on Putin and the Russian Federation investigation was re-energized, would be a public relations disaster.

Although, Mr Putin's lavish purchases go someway to detailing his financial situation.

Departing the White House Thursday, Trump said he was "very close" to a deal with China, but added, "I don't know that I want to do it, because what we have right now is billions and billions of dollars coming in to the United States in the form of tariffs or taxes".

Russia's Tass News Agency said these charges are punishable by up to six years in prison.

Ukrainian President Petro Poroshenko accused Putin on November 29 of wanting to annex all of Ukraine and called for North Atlantic Treaty Organisation to deploy warships to a sea shared by the two nations.

The United States and the European Union have imposed sanctions on Russia over its actions toward Ukraine since 2014, when Moscow annexed Crimea following the toppling of a pro-Russian leader in Kiev.

Ahead of the scheduled meeting, Trump's aides had previewed a broad agenda, though were vague on details. "I would love for this table - not Meghan included because she's different - to give him credit on something".

Trump routinely denounces Mueller's investigation as a witch hunt and the White House has said it has polluted American-Russian relations.

When Joy Behar started to argue, Meghan McCain backed Huntsman up by pointing out that the past three USA presidents have had fairly positive relationships with Putin.
