Asked whether she found the remark “condescending,” Ms. Bishop demurred and said she would not comment on the conversation between Mr. Trump and Ms. Macron.

“Likewise, I don’t run a commentary on his Twitter account,” Ms. Bishop said.

Ms. Bishop, who also serves as deputy leader of the right-leaning Liberal Party, has a reputation for being a steely politician who rarely breaks from party talking points.

As foreign minister, she has consistently made statements in support of Mr. Trump. “We share a common view on many issues, so we will continue to work very closely with the Trump administration,” Ms. Bishop said in January.

Mr. Trump has regularly commented on the appearances of women while on official duties as president. Last month, speaking on the phone with the new prime minister of Ireland, he interrupted his conversation to remark that a female Irish journalist “has a nice smile on her face.”
