Investing.com - Investors were busy fretting over the latest news coming out of Washington DC this week, amid growing uncertainty over the future of President Donald Trump.
Reuters reported Thursday that former National Security Adviser Michael Flynn and others on Trump’s campaign team exchanged at least 18 undisclosed phone calls or emails with Russian contacts during the 2016 presidential race.
That was only the latest worry in a tumultuous week at the White House, which included allegations that the president tried to interfere with a federal investigation and shared classified information with Russia's foreign minister.
The Justice Department on Wednesday appointed former FBI director Robert Mueller as special counsel to take over the investigation of Russia's alleged interference in the U.S. presidential election.
The recent string of controversies intensified doubts that Trump would be able to follow through on his campaign promises for tax cuts, deregulation and fiscal stimulus.
The deepening political turmoil triggered a sharp sell-off on Wall Street and sparked a rally in the widely-watched CBOE Volatility Index, which measures implied volatility of U.S. stock options and is often seen as an investor fear gauge.
