President Donald Trump is growing frustrated with demands to significantly boost the cap on the state and local tax deduction, according to a senior administration official, signaling a deadlock as Republicans aim to quickly pass a giant tax-cut bill.

The bill now faces a difficult test of making it through a Republican-controlled Senate with different preferences and priorities.

If the House provision is enacted, the SALT cap would rise to $40,000, up from $30,000 in the previous plan, and phase out over $500,000.
