The Republican-controlled state congress voted through the controversial changes on Wednesday night, Swedish time, after a lengthy debate. Before they become real, they also need to be approved by the state senate and signed by Governor Greg Abbott.
The proposal has been put forward at the request of President Trump with the intention of securing five new Republican seats in the House of Representatives and thus continued control over the Congress's lower house.
An intentionally racist map aimed at stealing millions of black and Spanish-speaking Texans' votes, has Gene Wu, the Democrats' group leader in Texas, previously said about the proposal.
Fled the state
The Democratic members of Texas tried to stop the vote by leaving the state at the beginning of August. They returned earlier this week, which made Wednesday's vote possible.
The decision to interrupt the protest came after California's Governor Gavin Newsom announced that his state will redraw its maps to the Democrats' advantage to balance out Texas's move.
Donald Trump, you have awakened the bear and we will strike back, said Newsom during a speech in Los Angeles last week and accused the president of trying to "rig" next year's midterm elections.
Obama praises
The move is praised by the US's former President Barack Obama, also a Democrat.
He has said that he will do it responsibly. We will not try to maximize it, says Obama during a fundraising event, according to AP.
In California, the changes must be approved by the state's voters in a special election planned for November 4.
Normally, the states' electoral districts are redrawn every tenth year based on new census data.
