(AP) — Last week, a furious mob overran the U.S. Capitol. This week, the fury is from within. Lawmakers are displaying searing anger over the attack and the catastrophic security failure that placed them in danger. And Democrats are livid over the fact that three of their lawmakers so far have tested positive for COVID-19 after they huddled for safety with Republicans during the assault. Several Republicans had refused to wear masks in that room. The rage is being stoked even hotter by the passions aroused by Democrats’ fresh drive to impeach President Donald Trump. One Democrat says this is a “powder keg” moment.
