HIGHLIGHTS-The Trump presidency on March 30 at 5:05 p.m. EDT/2105 GMT

March 30 (Reuters) - Highlights of the day for U.S. President Donald Trump's administration on Thursday: TRUMP VS. CONSERVATIVE REPUBLICANS Trump declares war on members of his own party by threatening the political careers of conservative Republicans who helped torpedo healthcare legislation he backed, but is quickly told the lawmakers will not bow to "bullying." RUSSIA Russia mounted a campaign of "propaganda on steroids" seeking to influence the 2016 U.S. presidential election, the top Democrat on the Senate Intelligence Committee says, listing several areas of concern about possible links to Republican Trump's campaign.

The White House has invited the top Republican and Democratic members of the Senate and House of Representatives intelligence panels to review new material relevant to their investigation into Russia's alleged interference in the election, presidential spokesman Sean Spicer says.

SURVEILLANCE Two White House officials played a role in providing House Intelligence Committee Chairman Devin Nunes with documents showing Trump and his associates were swept up in surveillance by U.S. intelligence agencies, the New York Times reports.

STRIKES IN SOMALIA The White House has granted the military broader authority to carry out strikes in Somalia against al Qaeda-linked al Shabaab militants, the Pentagon says, the latest sign Trump is increasing U.S. military engagement in the region.

SUPREME COURT Democratic Senator Joe Manchin says he will support the nomination of Judge Neil Gorsuch for a seat on the U.S. Supreme Court, giving Republicans the first of eight Democratic votes they would need to avoid a filibuster.

NAFTA The Trump administration will seek changes to the North American Free Trade Agreement allowing it to reimpose tariffs if a flood of imports from Canada and Mexico cause "a threat of serious injury" to U.S. industry, according a draft document sent to Congress.

SYRIA The United States is no longer making removing Syrian President Bashar al-Assad a focus of its policy in the war-torn country, the United States' U.N. ambassador says.

CLIMATE CHANGE The White House is reviewing the U.N. global climate accord and expects a decision on whether to remain a party to the deal by the time G7 leaders meet in late May.

KEYSTONE Several environmental groups sue the Trump administration in a federal court in Montana to challenge its decision to approve construction of TransCanada Corp's controversial Keystone XL pipeline.
