Cruz says McCain’s criticizing him because he backs Rubio

WEBSTER CITY, Iowa (AP) — Texas Sen. Ted Cruz said Thursday that fellow Sen. John McCain is calling for an exploration of his right to run for president because he intends to endorse Marco Rubio in the race.
McCain on Wednesday said questions about Cruz's eligibility due to his being born in Canada should be explored, keeping the issue alive after Donald Trump raised concerns about it earlier in the week. Cruz has dismissed the issue, saying it's part of the political "silly season" as Iowa's Feb. 1 caucuses near.
