* Questions about Trump's ability to prevail over Congress surfaced after Republicans were forced to withdraw a bill to reform the American healthcare system on Friday.
* However, losses on Wall Street were kept in check on hopes that Trump would be able to deliver on his pledge to lower taxes - a proposition that has driven a record-breaking rally on Wall Street.
* The White House late Monday said it would take a lead role in crafting legislation to reform the U.S. tax code, with an August target date.

* Federal Reserve Chair Janet Yellen speaks at a conference in Washington at 12:50 p.m. ET (1650 GMT) and could provide some insight into the timing of the central bank's next interest rate hike.
* Other Fed officials scheduled to make appearances include Fed Board Governor Jerome Powell, Dallas Fed President Robert Kaplan and his Kansas City counterpart, Esther George.
* Shares of Ford rose 0.96 percent at $11.57 in premarket trading after Trump tweeted that the U.S. automaker would make a major announcement regarding three plants in Michigan.
* Red Hat was up 4.7 percent at $86.10 in light premarket trading after the Linux operating system distributor reported quarterly revenue that beat analysts' expectations.
