Hillary Clinton faced an onslaught of questions about Israel from people describing the Jewish state's policies as "apartheid" on the campaign trail Thursday.

At her first stop in Columbia, S.C., a woman asked Clinton to comment on the United States' "$6 billion to fund Israeli apartheid," stating that we "spend too much money" on a country that does not have "shared values" with America.

Clinton chose not to answer the woman's question, but also not to rebuke it. This elicited criticism from Republican leaders who hoped to see Clinton reaffirm the strong alliance between the United States and Israel. When Secretary of State John Kerry referred to Israel as an "apartheid state" in 2014, his comments were widely condemned.

"That's not leadership and that's not how we stand up for our friend and ally Israel, but it is business as usual in today's Democrat Party," RNC spokesman Michael Short said. "It's becoming more clear that a Hillary Clinton presidency would be a rerun of President Obama's hostile approach, which included her serving as the White House's "designated yeller" at Israel as Secretary of State."

Clinton said she was "very concerned by attempts to compare Israel to South African apartheid" in a recent letter to Haim Saban, a top Jewish donor, saying she would condemn the Boycott Divest and Sanctions movement and support Israel if elected to the Oval Office.

While serving as secretary of State under President Barack Obama Clinton took numerous trips to Israel to help negotiate for a two-state solution between the Israeli and Palestinian people, though none of her attempts were successful.

Clinton was confronted about the Israeli-Palestinian conflict yet again while speaking in Greenville, S.C. An audience member asked Clinton if she believed a two-state solution between Israel and Palestine was possible. Clinton responded with a resounding "yes," stating that she believes a negotiated settlement is "the only resolution it will work."

Clinton talked about her meetings with President Barack Obama, Israeli Prime Minister Benjamin Netanyahu and Palestinian leader Mahmoud Abbas, while she was serving as secretary of state, saying that she felt they made progress, but once elected president she'd want to "go right back at it."

"The highest [priority] for Israel is security, the highest for the Palestinians is autonomy and independence and their own state," Clinton said, adding "We have to look for a way to persuade both sides to do more to demonstrate unequivocally their commitment to a two-state solution. And the are steps both sides can make that I would be promoting."

She added, "There is no alternative, and I will continue to work for that because I believe it is the best outcome for both Palestinians and Israelis in the region."
