A federal prosecutor has accused a lawyer for Boston Marathon bombing suspect Dzhokhar Tsarnaev joh-HAHR' tsahr-NEYE'-ehv) of trying to "encourage" a hung jury.

As jury selection resumed Thursday, Assistant U.S. Attorney William Weinreb said attorney David Bruck asked a "wholly inappropriate" question when he probed a man with a supervisory job about whether he would listen to the opinions of other jurors.

Weinreb told Judge George O'Toole Jr. he viewed Bruck's question as an "instruction" that no juror could change another juror's view about whether the death penalty would be an appropriate punishment.

Bruck said he was merely asking the juror if he understood that in the end, all jurors have to make their own decisions.

Tsarnaev is accused in the 2013 bombings that killed three people and injured more than 260.
