Minority Leader Nancy Pelosi sent a fifth letter to Democratic colleagues in a week in an attempt to bolster support for a measure to authorize a U.S. strike in Syria.

In the letter sent Saturday, Pelosi (D-Calif.) highlighted statements supporting the strike by President Barack Obama and Sen. Barbara Boxer (D-Calif.).

“Here in California, we are blessed with the leadership of Senator Barbara Boxer, who voted for the resolution marked up this week in the Senate Foreign Relations Committee,” Pelosi wrote to Democrats.
