Members of the Democratic Party reportedly prevented the $1 trillion coronavirus economic aid bill from moving forward on the Senate floor. The Republicans and the Democrats have, however, agreed to continue talks and agree on a solution regarding the same.
The likely political calculus involved is the Democrats want maximum financial disruption. They are likely afraid the economy will rebound quickly after this crisis. The delay will extend any virus related ressesion. Unfortunately for them the economic downturn may not get attributed to Trump.
