Dollar stutters as US tax debate grinds on; yen gains

TOKYO (Reuters) -The dollar struggled to regain its footing Tuesday as investor concerns over a sweeping tax and spending bill and its implications for the U.S. debt profile continued to undermine sentiment towards U.S. assets. Global stock markets and the euro gained on Monday while the United States was on holiday, after U.S. President Donald Trump delayed the imposition of tariffs on Europe. Attention now turns to debate in the U.S. Senate on Trump's tax-cut bill that is expected to add to the debt pile in the world's largest economy.
