Congress returns, under pressure to act on guns; War of words over Democrats' rebuttal memo

After a 10-day break that saw 17 killed during a Feb. 14 school shooting massacre in Parkland, Fla., Congress returns to work Monday under pressure to act on gun violence. But a plan of action may be elusive ...  No plan appears ready to take off, despite a long list of proposals, including many from President Trump, who told the nation's governors Sunday that the Parkland massacre will be a top priority in upcoming White House meetings. Republican leaders mostly have kept quiet for days as Trump tossed out ideas, including raising the minimum age to purchase assault-style weapons, strengthening background checks and arming teachers. 

The most likely legislative option may be bolstering the federal background check system for gun purchases. However, lawmakers may be skittish about that because opponents tie the measure with the movement to limit gun rights. Another X-factor is that lawmakers may feel a need to pivot back on immigration reform as DACA immigrants may face legal limbo if the Obama-era program is allowed to expire on March 5.
