WASHINGTON, Sept 11 (Reuters) - The U.S. budget deficit for August fell $35 billion or 9% from a year earlier to $345 billion as President Donald Trump's tariffs pushed net customs receipts up by about $22.5 billion for the month, the Treasury Department said on Thursday.

 

Receipts for August rose $38 billion or 12% to $344 billion, while August outlays grew $2 billion to $689 billion. Both receipts and outlays reached new records for the month.
