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 0.1 percent at $1,245.53 an ounce at 1131 GMT. The metal has risen 1.4 percent this week and on Thursday touched $1,253.12, its highest since Feb. 28. …Gold, seen as a safe haven asset, has benefited from falls in the dollar, U.S. bond yields and stocks as Trump’s difficulty in passing healthcare reform has undermined faith that he can deliver on promises of tax cuts and investment.
