Rep. Luna's investment in a donor's energy firm illustrates potential limits of a stock trading ban

WASHINGTON — At a Capitol Hill news conference last week, Rep. Anna Paulina Luna, R-Fla., threatened to force a vote on legislation banning lawmakers from owning or trading stocks, arguing members can’t represent their constituents when they are focused on their own investments. “Frankly, the fact that members are getting, what, plus-600% returns on their investments is wrong,” Luna said, flanked by both Democratic and Republican co-sponsors of the stock trading ban bill. “But more importantly, how could you ever be expected to represent your constituents when you’re clearly worried about your pocketbook?”
