NORTH CHARLESTON, South Carolina (Reuters) -Lara Trump, who Donald Trump has endorsed to be the new co-chair of the Republican National Committee, said on Wednesday that the organization needed to raise $500 million for the 2024 general election and did not rule out using raised funds to pay her father-in-law's mounting legal fees. Warning that the Democratic Party was flush with cash, Trump's daughter-in-law said the party needed a strong fundraising push to help Trump in his bid to return to the White House and for congressional races also up for grabs. Lara Trump made the comments at the Trump campaign's headquarters in North Charleston where she sought to rally supporters ahead of South Carolina's Republican primary on Saturday.
