May 12 (UPI) — The South Carolina Senate voted Tuesday against a measure to extend its legislative session to redraw the state’s congressional map. President Donald Trump has pressured lawmakers to move forward with redistricting to give Republicans an advantage.

Five Republicans joined Democrats in voting against the resolution, which would have extended the session by a week, NBC News reported. This would have given the Senate more time to vote on a plan that would break up the state’s only Black-majority district. The legislative session ends Thursday, and the state’s primaries are June 9.

The redistricting push by Trump comes after a U.S. Supreme Court decision in late April that badly weakened a key part of the landmark Voting Rights Act of 1965, one that had helped ensure minority groups could elect their choice of candidates.

State Sen. Shane Massey, a Republican and Senate majority leader, spoke out about the efforts before the vote, saying it’s a show of weakness to use redistricting to quash minority votes, Greenville News reported.

“My conscience is clear on this one,” Massey said. “I know what the right thing to do is.”

Massey said he’d received a call from Trump in recent days about pushing forward redistricting. On Monday night, Trump posted on social media that he was watching the vote closely.

“South Carolina Republicans: BE BOLD AND COURAGEOUS, just like the Republicans of the Great State of Tennessee were last week!” he wrote.

Last Thursday, the Tennessee state legislature passed a redistricting map that eliminated the state’s last Democrat-leaning, Black-majority district. Other Southern states have also been moving in this direction.

Senate Minority Leader Brad Hutto said the vote sends a message that the state rejects a White House power grab, Greenville News reported.

“The people of this state expect us to focus on real issues affecting their daily lives, not carry out an outside political agenda,” he said.

Later Tuesday, Republican candidates for governor in South Carolina criticized the members of their party who voted against the resolution.

Rep. Nancy Mace, who’s been endorsed by Trump for the governor position, posted on social media that the state needs “a Governor who the statehouse will fear and listen to.”

“You know I’d whip every single ‘NO’ vote into shape if I was Governor,” she posted.
