[Plugin: RSSImport] widget works but not the tag in a page

3 things:

First, you have a shortcode, use it! [RSSImport feedurl=”https://news.google.com/news?ned=us&topic=w&output=rss”%5D

Second, as highlighted here, the description (as of today) incorrectly states that comma (,) is the separator. Just use space ( ) instead.

Third, I had issues with URL having parameters (using the amp). I updated the function RSSImport_Shortcode() in file rssimport.php just before the $return by adding the line:
$feedurl = html_entity_decode( $feedurl );
