INDIANAPOLIS (AP) — Donald Trump’s running mate, Mike Pence, is brushing off Republican concerns of turmoil in their campaign.

In recent weeks, Trump has angered fellow Republicans by criticizing parents of a soldier killed in Iraq and refusing to endorse House Speaker Paul Ryan and others for re-election. The feud has overshadowed Trump’s criticism of Hillary Clinton.

Pence told NBC’s “Today Show” that he is seeing “tremendous enthusiasm” for the Republican ticket. He said “Donald Trump and I are standing shoulder to shoulder to say to the American people, ‘We can be strong again.'”

Pence also said Trump values the sacrifices made by military families: “This man has a heart for our soldiers.”
