Biden tops list of potential 2020 Democrats in new poll
Sen. Cory Gardner endorses Cruz
Gardner called Cruz "a fierce defender of the Constitution and a tireless advocate for conservative principles," according to a statement released by the Texas senator's campaign Wednesday.
Gardner added he was "thrilled" to support Cruz.
Cruz said he was "honored" to have the support of the Gardner, who is the sixth senator to publicly back Cruz, joining Jim Risch (R-Idaho), Lindsey Graham (R-S.C.), Mike Lee (R-Utah), Pat Toomey (R-Pa.) and Ben Sasse (R-Neb.).
"I am honored to have Cory's support and look forward to working together to continue to coalesce Republicans around this campaign," Cruz said in a statement.
The announcement comes amid speculation surrounding Cruz's plans to make a "major announcement" Wednesday afternoon in Indiana. Reports are indicating Cruz will announce his choice of Carly Fiorina to be his running mate. Fiorina, a former Hewlett-Packard CEO, dropped her own White House bid earlier this year.
Cruz is hoping to deny GOP front-runner Donald Trump delegates in the Indiana primary next week after the businessman moved closer to locking up the GOP nomination by winning five Northeastern primaries Tuesday.
