From the London Mail [caution tabloid]:
Marco Rubio was forced on the defensive last night after a bipartisan group of senators claimed he told them the US’s peace plan for Ukraine was authored by Russia.
The US Secretary of State denied their account, with a spokesman calling it “blatantly false”, but the dispute threatens to derail President Trump’s push for a peace deal to be achieved this week. Rubio took the extraordinary step of suggesting online that the senators were mistaken, even though they said he was their source for the information. The secretary of state doubled down on the assertion that Washington was responsible for a proposal, which has faced push back in Europe for being so favorable to Moscow.
