A Texas Democratic lawmaker is scheduled to attend a conference at the White House on voting rights.
Rep. Trey Martinez Fischer was the only Texan invited to Monday's meeting in Washington with President Barack Obama.
Last week the Justice Department announced it would support a lawsuit asking a federal judge to require Texas to pre-clear all new election laws in the state. Attorney General Eric Holder said because Texas had a recent history of intentional discrimination against minorities, it needed special attention.
Martinez Fischer is one of the plaintiffs in a voting rights lawsuit in San Antonio that challenges new election maps. A three-judge panel is considering whether it needs to draw new maps to make sure minorities are fairly represented.
Texas primary elections are scheduled for March 4.
