From the Beeb:

Donald Trump’s personal lawyer, Michael Cohen, received a secret payment of at least $400,000 (£300,000) to fix talks between the Ukrainian president and President Trump, according to sources in Kiev close to those involved.

The payment was arranged by intermediaries acting for Ukraine’s leader, Petro Poroshenko, the sources said, though Mr Cohen was not registered as a representative of Ukraine as required by US law.

The meeting at the White House was last June.

Shortly after the Ukrainian president returned home, his country’s anti-corruption agency stopped its investigation into Trump’s former campaign manager, Paul Manafort.

Cash and carry diplomacy; what could go wrong?

A high-ranking Ukrainian intelligence officer in Mr Poroshenko’s administration described what happened before the visit to the White House.

Mr Cohen was brought in, he said, because Ukraine’s registered lobbyists and embassy in Washington DC could get Mr Poroshenko little more than a brief photo-op with Mr Trump. Mr Poroshenko needed something that could be portrayed as “talks”.

And for that you gotta pay actual folding money.
