If Colorado National Guard troops are used to keep a look out for illegal immigrants, it won't be the first time in the state's history.
Seven decades ago, Democratic Governor Edwin Johnson sent troops to the state's southern border to prevent job-seeking Mexicans from coming in and taking Colorado jobs.
Historians say the April 1936 ban lasted for two weeks, when Johnson relented amid criticism, including the threat from New Mexico to boycott Colorado products.
Historians say doing a similar blockade would be illegal in today's society, but the circumstances of why it was done then are still here.
President Bush today sent Congress a 1.9 billion dollar request to pay for the temporary deployment of up to six-thousand National Guard troops to the U.S. Mexico border.
Bush's request would also help pay for new fencing and other barriers as well as two new unmanned surveillance aircraft and five helicopters to curb illegal immigration.
Johnson, called "Big Ed," served three terms as governor and three terms in the Senate.
He died in 1970.
