Some of you might be aware that the whitehouse.gov has a website where regular people can start a petition. If a particular petition receives at least 100,000 signatures, it MUST be addressed by the government.
Someone started a petition to place a moratorium on all Syrian Refugees into the US until things are figured out, stating that at least one of the Paris terrorists was a Syrian refugee and got through their vetting process. This is also possible for refugees coming to the USA.
What is more, the Federal Government will determine how many refugees are sent to each state, and they will not share information about the refugees with the states, such as background checks, etc.
Please go to the whitehouse.gov's website and sign the petition.
