WASHINGTON — Sen. Elizabeth Warren is proposing a bill that would prevent members of Congress from owning individual stocks.

“Enough with the spectacle of HHS secretaries and herds of congressmen caught up in insider trading schemes,” she said. “It’s time to ban elected officials and senior agency officials from owning or trading stocks while in office.”

Warren was alluding to the recent arrest of Rep. Chris Collins (R-NY) over alleged insider trading of stock in Innate Immunotherapeutics, which also counted former Health and Human Services Secretary Tom Price as an investor.

“They can put their savings in conflict-free investments, like mutual funds, or they can pick a different line of work,” Warren said at the National Press Club.

Warren’s speech — about a number of anti-corruption measures she’d like to implement — had all the markings of a presidential stump speech.

But the Massachusetts senator denied she was eyeing the White House in two years.

“I am not running for president in 2020, I am running for Senate in 2018,” she told the crowd, shaking her head when introduced as a likely Democratic hopeful.
