Rep. Gwen Moore (D-WI) said Monday that while Cruz was cordial on board the flight to South Africa, she and others were "curious" about what motivated the tea party senator to join the delegation.
"I think that he was on the spot because there were many members who were curious, you know, about why he would want to take this pilgrimage," Moore said on MSNBC. "This was a solemn — it was hard trip, 40 hours and turning right around. And even the senator had to come right back and vote at 1 a.m."
Moore pointed out that the delegation was comprised mostly of Democrats, including some lawmakers who were active in the anti-apartheid movement.
"And so there was a lot of curiosity about [Cruz]," she said.
Rep. Elijah Cummings (D-MD), who was also in the delegation, said last week that Cruz "got an earful" from his Democratic counterparts on the flight.
