Mr McConnell tweeted, His memory continues to remind me every day that our nation is sustained by the sacrifices of heroes.
Senator Johnny Isakson of Georgia said not only the McCain family but the nation deserves better than Mr Trumps disparagement.
I dont care if hes president of the United States, owns all the real estate in New York, or is building the greatest immigration system in the world, Mr Isakson told The Bulwark, a conservative news and opinion website.

Utah Senator Mitt Romney, the Republican 2012 presidential nominee whom Mr Trump briefly considered nominating as secretary of state, tweeted praise for Mr McCain on Tuesday – and criticism of Mr Trump.
I cant understand why the President would, once again, disparage a man as exemplary as my friend John McCain: heroic, courageous, patriotic, honorable, self-effacing, self-sacrificing, empathetic, and driven by duty to family, country, and God, Mr Romney wrote.
Pushback also came from Senator Martha McSally, a Republican Air Force veteran appointed to Mr McCains seat from Arizona.
John McCain is an American hero and I am thankful for his life of service and legacy to our country and Arizona, she tweeted Wednesday.
Everyone should give him and his family the respect, admiration, and peace they deserve.
Senator Lindsey Graham, who wept openly on the Senate floor after Mr McCain died but has allied himself strongly with Mr Trump, said, I think the presidents comments about Senator McCain hurt him more than they hurt the legacy of Senator McCain.
