U.S. stocks ended higher on Tuesday as investors awaited the minutes from the Federal Reserve's latest meeting scheduled for Wednesday.

The Dow Jones Industrial Average increased 63.60 points, or 0.25 percent, to 25,822.29. The S&P 500 increased 5.91 points, or 0.21 percent, to 2,862.96. The Nasdaq Composite Index rose 38.17 points, or 0.49 percent, to 7,859.17.

Investors kept a close eye on the minutes for more clues on the Fed's policy plans on interest rates.

Multiple media outlets on Monday reported that U.S. President Donald Trump said he would continue criticizing the Fed should it continue to raise short-term interest rates, which the central bank has indicated it will do at a steady clip.

The Fed's annual economic symposium that will start later this week in Jackson Hole in the U.S. state of Wyoming is also in focus.

Fed Chair Jerome Powell is due to deliver a speech on Friday, and the summit will be themed around the idea of changing market structure and the implications for monetary policy going forward.

There was no major economic data on Tuesday.
