Sen. Ted Cruz (R-TX) on Monday called on America’s grassroots conservative activists to rise up and organize an effort against the Washington, D.C. establishment to defund Obamacare in the upcoming Continuing Resolution (CR) that funds the government and must be voted on by the end of September.

In his “Freedom Minute” segment he distributes regularly to various media and radio outlets, Cruz said he needs a “grassroots army” to help him fight. He walked through how a year ago last week was the anniversary of him winning the GOP primary in Texas for U.S. Senate against all odds because of the grassroots support he received.

“Today I work for 26 million Texans, and your support is why I’m serving in office helping lead the fight to protect the Second Amendment, to secure the border, and to unshackle the free market economy,” Cruz said.

“Now we need to activate another grassroots army–this time on a national scale. In September, Congress will have the opportunity to defund Obamacare–the disastrous health care law, which is killing jobs and hurting the health care system. The only way we can win this debate is if the American people rise up and demand it. Please join us and let your representatives know where you stand.”
