WASHINGTON (Reuters) - From solar-powered bikes to aid for an African country that spent millions on a massive monument, US Republican lawmakers on Wednesday cited lots of candidates for cutting US foreign aid. Lawmakers berated US foreign aid officials at a congressional hearing, highlighting the challenge the Obama administration faces as it tries to shield foreign assistance from spending cuts sought by the Republican-led House of Representatives. "Why are the US taxpayers going to buy a solar-powered bicycle? How is that going to help out the world?" demanded Representative Donald Manzullo, an Illinois Republican, at a hearing of the House Foreign Affairs Committee. Manzullo found a description of the bike project on the website of the US Agency for International Development (USAID), which along with the Millennium Challenge Corp. (MCC) delivers US development assistance around the globe. USAID's website says a $100,000 grant went toward development of the "E-bike" - "practical, scalable, pollution-free mobile transportation." USAID Administrator Rajiv Shah said the grant came from a new venture capital-style investment fund supporting research into technologies that can help the developing world. "I don't know any American who can afford to buy a solar-power bicycle themselves. This is a waste of taxpayers dollars, and the sooner you guys wake up and understand that, the better off you are going to be," Manzullo said. Republicans, who took control of the House in November elections, have called for a tough look at non-military overseas spending amid calls to control the federal deficit. Shah, defending the foreign aid budget for 2012, argued that foreign assistance is linked to national security and costs less than one percent of the nation's total budget. "By improving global stability, our foreign assistance helps keep America safe," he said. President Barack Obama requested $55.7 billion for the State Department and foreign aid in fiscal 2012, which starts in October. This includes $8.7 billion in funds for aid and diplomatic operations in Afghanistan, Pakistan and Iraq. Republican Representative Sam Poe unfurled a large map of the world and announced that all countries that got some kind of US foreign assistance were colored red. Most of the world was red. "Many of these, they don't even like us," Poe said. "We don't need to pay people to hate us, they'll do it on their own." He proposed an up-or-down vote on each country as Congress decides who should get foreign aid. Another Republican, Ed Royce, asked why the Millennium Challenge Corp. had awarded $540 million to Senegal, a country that last year spent some $28 million on an "African Renaissance" monument larger than the US Statue of Liberty. Royce complained the statue was manufactured in Communist North Korea. "Our US taxpayers put money into Senegal and that frees up money for this kind of an operation." "In terms of the statue, those things happen," Millennium Challenge Corp CEO Daniel Yohannes responded. "We're not happy about it."
