Wall Street dropped amid concern about US President Donald Trump's ability to deliver on his promises to cut taxes and regulations.
Trump warned fellow Republicans in the House of Representatives they would face "political problems" for opposing the bill that takes apart Obamacare and partially replaces it, Reuters reported. The House is set to vote on the American Health Care Act on Thursday.
"If we are not able to move forward with health-care reform, it endangers tax reform," Representative Bill Flores of Texas, a former chairman of a House conservative caucus, told Bloomberg on Friday. "The folks that were able to tear this down would feel like they're empowered to tear the next big project down."
In 1.43pm trading in New York, the Dow Jones Industrial Average shed 0.9 per cent, while the Nasdaq Composite Index dropped 1.4 per cent. In 1.28pm trading, the Standard & Poor's 500 Index slid 1 per cent.
"Republicans should have prioritised tax reform ahead of healthcare reform," Brian Jacobsen, chief portfolio strategist at Wells Fargo Funds Management in Menomonee Falls, Wisconsin, told Reuters. "They're coming across as a motley crew rather than a party that can get things done."
