Gold was on track for a second weekly gain on Friday as concern about the ability of U.S. President Donald Trump to push legislation through Congress held the dollar near 7-week lows, making bullion cheaper for holders of other currencies.
Spot gold was up 0.29 percent at $1,248.36 per ounce. On Thursday, it touched its strongest since Feb. 28 at $1,253.12. The yellow metal was on track for its second straight week of gains.

Gold prices have been supported by expectations that the Fed will raise interest rates more slowly than some had feared.
Higher rates tend to pressure gold by lifting the opportunity cost of holding non-yielding bullion and boosting the dollar, in which gold is priced.
Bullard said on Friday that just one more rate hike this year would be appropriate following a rise earlier this month, but that he would not fight a second one. Dudley said that "delicate" policy changes were necessary.
