Governor Doug Ducey and his wife greeted the hearse along with a phalanx of military personnel, war veterans, law enforcement officers and firefighters in dress uniform. John McCain is getting so much media attention in the wake of his death on Saturday. The late senator's desk served as a makeshift memorial, and Cindy McCain shared a photo of the memorial on Twitter.
During Wednesday's private service at the Capitol for family and friends, Cindy McCain pressed her face against her husband's coffin, and daughter Meghan McCain erupted in sobs.
"Given the political world as it is today, why go do this?"
McCain, who died on Saturday, is expected to taken by military transport to an air base outside Washington - just as Trump is holding a rally in IN on Thursday.
On Wednesday, a private service was held at the Capitol for family and friends.
Ducey said McCain's fight for America wasn't over adding "it's a fight all Americans are obligated to continue on his behalf". But under pressure from military veterans and members of Congress, Trump finally issued a statement on Monday saying he respected McCain's service to the country and had ordered flags to half-staff.
Gov. Doug Ducey remembered McCain as "Arizona's favourite adopted son" on what would have been his 82nd birthday.
Nazanin Zaghari-Ratcliffe sent back to prison as release are hopes dashed
Mrs Zaghari-Ratcliffe's family have previously criticised the United Kingdom government for not negotiating her release. Her four-year-old daughter, Gabriella, cried when she realised her mother was leaving.
The 44-year-old says she's been following the longtime senator since she was 18 and always voted for him despite her party affiliation.
"I saw him as a prisoner in a cage", she said of McCain.
Arizona National Guard members carried the casket into the Arizona State Capitol Museum rotunda, where McCain will lie in state.
Schumer and Arizona's junior senator, Jeff Flake, will formally introduce the resolution soon.
McCain's motorcade is expected to depart the church, following the service, at about 11:15 a.m. for Phoenix Sky Harbor International Airport where the senator will leave Arizona for the final time.
Twenty-four sitting US senators, four former senators and other leaders from Arizona were expected at the service for the maverick politician, former prisoner of war and two-time presidential candidate.
Former Presidents George W. Bush and Barack Obama will speak at a Saturday memorial service at Washington National Cathedral.
Trump and McCain have feuded for years.
Tomorrow, McCain's body will be flown to Washington D.C., where he will lie in state at the Capitol Rotunda before he's lain to rest at the U.S. Naval Academy Cemetery.
