Donald Trump on Thursday intensified his attacks on Republican leaders in Congress, this time blaming them for leading the country closer to the economic calamity of a spending crisis and debt default.

Congress has until September 29 to raise limits on government borrowing or face financial turmoil.

This week Mr Trump has turned his fire repeatedly on his own team. Critics say is isolating himself from the officials he needs to pursue his agenda, while supporters insist it is all part of his election promise to shake up Washington.

In a series of tweets, the President singled out Mitch McConnell and Paul Ryan, who lead Republicans in the Senate and the House respectively, accusing them of being responsible for a “mess”.

He said he offered them a chance to write the necessary legislation into a bill to help military veterans which he has since signed into law.
