Highlights: The Trump presidency on March 29 at 6:18 p.m. EDT

(Reuters) - Highlights of the day for U.S. President Donald Trump's administration on Wednesday: RUSSIA The leaders of the U.S. Senate Intelligence Committee jointly pledge that their investigation of Russian hacking of the 2016 U.S. election campaign will be bipartisan, a sharp contrast to bitter partisan disagreement surrounding a similar probe in the House of Representatives. CLIMATE CHANGE Nations led by China and the European Union rally around a global plan to slow climate change after Trump began undoing Obama-era plans for deep cuts in U.S. greenhouse gas emissions. MIDDLE EAST PEACE After weeks of heightened unease over the stance of the United States under the new administration, Arab leaders reaffirm their commitment to a two-state solution to the decades-long Arab-Israeli conflict. TAX OVERHAUL Raw feelings and mistrust could pose an obstacle to Trump and hardline conservative lawmakers in his Republican Party as they seek to rebound from defeat on healthcare legislation by launching into an overhaul of the U.S. tax code. U.S. STOCKS Wall Street has tempered its expectations for sweeping U.S. tax cuts in the wake of Trump's stinging healthcare defeat, a move that could push investors to embrace cheaper global stocks after the heady U.S. rally of recent months. HEALTHCARE Republicans mostly blame the U.S. Congress, and not Trump or party leaders, for failing to pass their party's healthcare overhaul, according to a Reuters/Ipsos opinion poll. INTERNET PRIVACY Trump plans to sign a repeal of Obama-era broadband privacy rules as a bigger fight looms over rules governing the openness of the internet, the White House says. FEDERAL LANDS A Native American tribe in Montana sues the Trump administration, challenging its decision to lift a moratorium on coal leases on public land without first consulting with tribal leaders. The Interior Department says it will form a committee to review royalty rates collected from oil and gas drilling and coal mining on federal lands to ensure taxpayers receive their full value. IVANKA TRUMP Ivanka Trump says she will work in the White House in an unpaid, informal advisory role to her father the president as she seeks to allay ethics concerns about working there. TRUMP UNIVERSITY A U.S. judge will hear arguments on Thursday over whether to grant final approval to a $25 million settlement of fraud lawsuits against the president over his Trump University real estate investment seminars, with at least one former student objecting to the deal.
