Secure the borders to prevent terrorist from accessing the United States via Mexico. It is too easily accessible

Terrorist can enter Mexico much easier than the United States, with that terrorists can easily then go from Mexico and cross into the US like millions of illegal immigrants do daily. The fence and border security is not to just keep out illegal immigrants but to keep out anyone who would plan to harm Americans by accessing us thru a country who's security at airports, ports, and all means of entry are not as well patrolled or protected as ours. Please keep Americans safe by securing our borders
