Conservative Republican senators will be using the August recess to organize a “grassroots army” to put pressure on Republican leaders, particularly Senate Minority Leader Mitch McConnell (R-KY), to defund Obamacare during the budget negotiations that will ensue when they return to Washington.

As Breitbart News reported, Sen. Ted Cruz (R-TX) has called for such a “grassroots army” on the national scale to stop Obamacare and comprehensive immigration reform.

Cruz (R-TX), along with Senators Mike Lee (R-UT), and Marco Rubio (R-FL), are leading the effort to defund Obamacare, which currently has the support of 13 Senate Republicans. Cruz and Lee have been promoting an online petition, www.dontfundobamacare.com, that already has over 250,000 signatures. They want to put pressure on McConnell to join them in supporting a measure to fund the government except for Obamacare.
