Largely peaceful anti-Trump protests continued a second night in several American cities, except for the one in Portland, Oregon, where police arrested at least 26 people.

Portland police said they treated the protest as "a riot" due to the "aggressive" crowd of about 4,000 and "extensive criminal and dangerous behaviour".

Demonstrations have been on- going in major cities across the country, including New York - where 65 arrests were made on Wednesday night - and Chicago, and even on college campuses in typically Republican states such as Texas, after Mr Trump was named President-elect on Wednesday.

After accusing the demonstrators of being "professional protesters" incited by the media, he later praised them for their "passion".

"Love the fact that the smaller groups of protesters last night have passion for our great country. We will all come together and be proud!" he tweeted.

The President-elect yesterday also tweeted that he "will soon be making some very important decisions on the people who will be running our government!"

Some names that have been tossed up include his campaign manager Kellyanne Conway and his son-in-law Jared Kushner.
