Details of Secret Service Breaches Evolve

WASHINGTON (AP) — A senior Democratic lawmaker wants Secret Service Director Julia Pierson to leave her post after a series of embarrassing presidential security breaches.

Rep. Elijah Cummings of Maryland says he does "not feel comfortable with her in that position." Cummings is the ranking Democrat on the House Oversight and Government Reform committee. He notably did not call for Pierson's firing or resignation during a congressional hearing Tuesday.

Cummings is believed to be the first member of Congress to call for Pierson's ouster. He made his comments during an MSNBC interview Wednesday morning.

Pierson testified Tuesday before Cummings' committee about a Sept. 19 White House security breach and Cummings and other law makers said they were unimpressed with her explanations.
