The Trump administration will send 1,000 more troops to the country's southern border, with the goal being to have a total of 6,000 troops stationed at the border by March 1.
The newly-deployed troops will lay down concertina wire and help install monitoring devices between various ports of entry.
According to the Pentagon, over 2,000 of the 5,000 troops currently at the border belong to the National Guard because of a strain on the Border Patrol. However, the governors of California and New Mexico recently ordered the withdrawal of guardsmen from their borders, meaning that the number of guardsmen deployed could soon decrease.
The troop deployment comes after Trump's recent declaration of a national emergency at the country's southern border, a move made with the aim of circumventing Congress in order to gain funding for his long-promised border wall.
House Speaker Nancy Pelosi has announced there will be a vote on Tuesday on a measure that would block the national emergency declaration.
