US President Donald Trump's fury over a border wall continues to flare as he blames Mexico for failing to stop caravans from marching into the U.S., Daily Mail reported.

'Mexico is doing NOTHING to stop the Caravan which is now fully formed and heading to the United States,' he tweeted Saturday morning. 

'We stopped the last two - many are still in Mexico but can’t get through our Wall, but it takes a lot of Border Agents if there is no Wall. Not easy!' he added. 

His tweet comes as the partial government shutdown enters its 29th day and as he prepares to deliver a speech Saturday afternoon rallying yet again for his controversial border wall that Democrats have continuously rejected.
