Investing.com - The U.S. dollar slipped lower against other major currencies on Friday, pulling away from a one-week high following news of potential personnel changes at the White House, sparking fresh concerns over U.S. political turmoil.
The greenback weakened after the Washington Post reported on Thursday that U.S. President Donald Trump has decided to replace his national security adviser, H.R. McMaster.
Markets were already jittery following the President's decision on Tuesday to fire Secretary of State Rex Tillerson.
Adding to concerns over U.S. politics, fears of potential trade wars were reignited after Donald Trump announced plans this week to impose tariffs on up to $60 billion of Chinese imports, specifically targeting the technology and telecommunications sectors.

The euro and the pound were higher, with EUR/USD up 0.11% at 1.2319 and with GBP/USD adding 0.08% to 1.3947.
