March 25 (Reuters) - Wall Street's main indexes were set toopen slightly lower on Monday, as investors struggled to shrugoff global growth fears even as a report showed that PresidentDonald Trump's campaign did not collude with Russia.
S&P 500 futures initially rose on Sunday after SpecialCounsel Robert Mueller found no evidence of collusion, but thereport left unresolved the issue of whether Trump obstructedjustice by undermining the investigations that have dogged hispresidency. urn:newsml:reuters.com:*:nL1N21B02H

"The concerns of global growth, without a China-U.S. tradedeal, will linger in the background and continue to weigh onmarkets."
