Democratic presidential candidate Sen. Elizabeth Warren (D-Mass.) appeared flustered Wednesday when asked whether her ethics proposal unveiled this month would prohibit her vice president’s son from serving on the board of a foreign company, as was the case under President Barack Obama.

“Could you say whether or not, under a Warren administration, would your vice president’s child be allowed to serve on the board of a foreign company?” asked a reporter following the Massachusetts senator’s speech at a New Hampshire rally.

“No,” Warren initially answered. Then she backtracked. “I don’t know. I mean I’d have to go back and look at the details.”

The far-left senator branding herself as the maven of comprehensive proposals released a plan dealing with Washington corruption earlier this month. She’s making a play for rival 2020 White House hopeful Sen. Bernie Sanders (I-Vt.) supporters and picking up momentum.

Warren said she was uncertain, however, whether her new proposal would bar the situation that occurred during the Obama administration: Vice President Joe Biden’s son, Hunter, sat on the board of a Ukrainian energy company for $50,000 a month despite having no prior experience in the industry. Meanwhile the vice president was managing the administration’s Ukraine policy and pressured the Ukraine government to end a corruption probe into the company.

Warren rolled out her corruption plan with announcing the Working Families Party’s endorsement during one of the largest speeches of her campaign to date, speaking to an estimated audience of 20,000 people gathered in New York City’s Washington Square Park last week. The endorsement from the Working Families Party, an openly socialist group connected to Communists, struck a blow to Sanders because the organization backed the Vermont senator’s presidential bid in 2016.
