President Donald Trump declared America's relationship with Russia at an "all-time and very dangerous low," and blamed Congress for it.

Mr Trump's comments came a day after he reluctantly signed into law new sanctions against Moscow that had been overwhelmingly approved by Congress.

The president also escalated his attack on Congress, which is controlled by his own Republican party, blaming the legislative body for its failure to overhaul the us healthcare system.

Mr Trump, wrote on Twitter: "Our relationship with Russia is at an all-time and very dangerous low. You can thank Congress, the same people that can't even give us healthcare!"
