Newly empowered House Democrats are flexing their strength with blossoming investigations. A half-dozen House committees are now probing alleged coordination between Trump associates and Russia's efforts to sway the 2016 election, Trump's tax returns and possible conflicts of interest involving the Trump family business and policy-making. The House oversight committee, for instance, has set a Monday deadline for the White House to turn over documents related to security clearances after The New York Times reported that the president ordered officials to grant his son-in-law Jared Kushner's clearance over the objections of national security officials.
