Sometimes the small lies mask big lies, and we often spend so much time chasing the small ones that we let the big ones slide past, uncorrected and even undetected. Little by little, President Donald Trump's most ardent defenders have smuggled a big lie into the ongoing political debate, and it isn't attracting any scrutiny.
That big lie is this: Democrats in Congress who have launched a new round of hearings and other oversight efforts on Trump are abusing their power, because they lack evidence or reasonable suspicion of crimes before conducting investigations.
This completely misstates the core purpose of congressional oversight.
